Of course! Without decimals, you couldn't calculate percentages or fractions. Decimals allow you to break a number up. A decimal is basically a fraction, and when you calculate fraction adding, subtraction, multiplication, and division, sometimes it is easier to calculate a fraction by first changing it to a decimal instead.

What is the relationship between integer's whole number's and counting number's?
"Integers" are all numbers, positive and negative, that aren't fractions or decimals. Examples: -3,-2,-1,0,1,2,3,57, 109349503... Whole numbers are all positive integers. (Including zero, which looks like a "hole". haha.) Examples: 0,1,2,3,4... counting numbers are just like whole numbers except they don't include zero. Also known as "natural" numbers. It's like what people naturally count. Examples: 1,2,3,4... They are ALL integers though...no fractions or decimals.
