Calculating 0.9 of 90

Hey there! Today, we're going to learn how to find 0.9 of 90. It sounds tricky, but we'll take it step by step, and you'll see how easy it can be!

Step 1: Understanding Decimals

First, let's talk about what 0.9 means. The number 0.9 is the same as 9 out of 10. You can think of it like this: if you have 10 candies and you eat 9, you have eaten 0.9 or 90% of your candies!

Step 2: Finding 10% of 90

Next, to find 0.9 of 90, it helps to first find 10% of 90. To find 10% of a number, you can divide it by 10. So, for 90:

90 ÷ 10 = 9

This means that 10% of 90 is 9.

Step 3: Finding 90% of 90

Now, since 0.9 is the same as 90%, we can find 90% of 90. To find 90%, we can just take 90 (which is 100%) and subtract 10% (which we found out is 9):

90 - 9 = 81

This tells us that 0.9 of 90 is 81.

Conclusion

So, when you hear 0.9 of 90, remember it means you are taking away just a little bit (the 10%) from 90, and what you get is 81.

Good job following along! Now you can easily find 0.9 of any number!
