Answer:
1. 18
2. 72
3. 90%
Step-by-step explanation:
For number 1
To find percentage you multiply the total number of kids with the percentage.
To do this you have to convert the percent into a decimal by moving the dot 2 times from its original location Ex. 20% = .20 as 20 would look like 20.00 in decimal form.
So .20 x 90 = 18
For number 2
Subtract 18 and 90 to find the remanding kids
For number 3
Divide 72 and 90. Make sure the lower number is being divided.
The answer you will get is .8 so move the decimal back two times because you are converting it to a percentage."
You will then get 80.00 as an answer then from there turn it to a percentage
80%
