How To Write 1 Cent In Decimals

Lesson ane: Introduction to Decimals

What are decimals?

A decimal is another fashion to write a fraction. Y'all tin think of a decimal every bit a function of a whole number. It is less than i whole thing, but more than 0 .

You may not realize it, simply you see decimals a lot in existent life. Ane of the most common examples is money.

Do you recognize these coins? We have a quarter, a dime, and two pennies. Yous could write each of these as a decimal. That'south because each coin is worth less than a whole dollar.

Click through the slideshow to learn how decimals work.

This is a dollar. A dollar represents a whole number. It is equal to 1.
We could besides write that as i.00. In other words, 1 = 1.00.
one.00 is a decimal. Here, information technology means nosotros have 1 dollar and 0 cents.
As you may already know, there are 100 pennies in a dollar. This ways 100 pennies equals 1.00.
One penny is part of a dollar. More than specifically, information technology's i cent. Nosotros could as well write that as a decimal: 0.01.
Permit's look at a few more decimals. ix cents is 0.09 of a dollar.
A quarter, or 25 cents, is 0.25 of a dollar. Any time y'all have part of a whole, you tin write it as a decimal.
Let's await at some other example. This pitcher holds 1 liter of water. Right now it'due south full.
Nosotros could write this as a decimal: 1.00 liters.
The pitcher is split into 10 parts. This means each part is equal to 0.ten liters.
Equally the day goes on, the bullpen gets emptier. At present it has 0.lxx liters. That's because nosotros used up 0.xxx liters.
Now it has 0.fifty liters, or half a liter.
Now it has 0.xx liters. Even though we have less than one liter, nosotros have more zero liters, so we can write information technology equally a decimal.

Reading decimals

As you saw on the last page, decimals look a lot similar a regular numbers, with a few important differences. First, all decimals have a decimal point ( . ). The decimal bespeak looks like a period. Any number to the left of the decimal point is a whole number. The numbers to the right are like a fraction—they're less than 1 whole merely more than 0.

For instance, let'southward take a await at this decimal.

9.6

ix is on the left of the decimal point, so we have 9 whole things. 6 is on the correct, so we likewise take 6 parts of a whole.

Nosotros encounter written decimals all the time in real life. For example, you lot might know that the average body temperature is 98.6 degrees. Or you might tune in to a radio station like 97.5. Merely do yous know how to read these decimals out loud?

Click through the slideshow to learn how to read decimals.

Let'southward try reading this decimal: 9.6.
Kickoff, we'll read the number to the left of the decimal point. That's nine.
Next, we'll read the decimal point. Usually, you'll just say "point ".
Finally, we'll read any number to the right of the decimal point. That's six.
So, we'd read 9.half dozen like this: nine bespeak half-dozen.
But you lot could also read it like this: nine and half-dozen-tenths.
When you read decimal numbers, each identify to the right of the decimal point has a special proper name.
The place immediately to the correct of the decimal bespeak is the tenths identify.
Here, the decimal means we accept .half-dozen, or half-dozen-tenths, of a whole.
You might think from Introduction to Fractions that vi-tenths is just another manner of proverb 6/10.
So ix.six means we have 9 whole things and 6/10, or six-tenths, of another matter.
Since we have nine and six-tenths, the give-and-take "and" replaces the decimal point.
Let'south try some other instance. How would you read this decimal? 0.25.
We can read 0.25 as nothing point two v...
We tin can read 0.25 as zippo betoken 2 five...or leave out the zero and just say point two v.
But we could also read it like this: twenty 5-hundredths.
Let's look at our decimal places again. 2 is in the tenths identify, so we take two-tenths.
Adjacent is the hundredths place. In this case, 5 is in the hundredths place, so we have five-hundredths.
When we read this number aloud, we'll say the 2 and five together as "twenty-v ".
We'll also say the decimal place that is farthest to the right. In our example, that's the hundredths place.
And then nosotros'll read 0.25 as twenty v-hundredths.
This is just another way of writing 25/100.
To figure out how many hundredths we had total, we could have added these numbers: two-tenths and five-hundredths.
ii tenths is the aforementioned as 0.twenty , or xx-hundredths.
0.twenty plus 0.05 equals 0.25, or twenty 5-hundredths.

Endeavor This!

Decimals and money

What if you had to read this decimal out loud?

Fifty-fifty though nosotros use decimals when we use coin, nosotros read them slightly differently. Instead of three point two three, or three and twenty iii-hundredths, we'll say three dollars and twenty-iii cents.

You could likewise read information technology similar this: "3 twenty three ". To save time, virtually people get out out the decimal bespeak when talking about money. How about $v.99? That would be five dollars and ninety-9 cents, or five 90-ix.

Remember, these rules only piece of work with money. They can't be used to read other decimals.

Endeavour This!

Try reading these dollar amounts.

Comparing decimals

Permit's imagine you're shopping for a new water pitcher. You find two y'all like—one holds 0.7 gallons, while the other holds 0.v gallons. Exercise y'all know which pitcher is larger? Click the arrows to observe out.

To find out which bullpen holds more, you could simply compare the decimals to run across which is larger.
7 is larger than 5, and then 0.7 is larger than 0.5. The larger the number to the right of the decimal betoken, the larger the decimal.

How about these two decimals:

Over again, yous'll only compare the numbers to the right of the decimal point.
74 is larger than 72, then 0.74 is larger than 0.72.

Now permit'due south compare these decimals:

Since the whole number, 1, is the same for both decimals, we'll compare the numbers to the right of the decimal point.
If you idea .two was larger than than .xix, yous were right!
Remember, one.2 could likewise be written as 1.20.
twenty is larger than 19, so one.20 is larger than 1.19.
