Because not all things are whole units.
They are all the same, fractions can be turned into percents and percents can be turned into fractions. hope that helps :)
No, they are not.
Convert the fraction into a decimal and then multiply it by 100 to turn it into a percentage as for example 3/4 = 0.75 as a decimal and 0.75*100 = 75%
Percents are hundredths. To change a percent to a fraction, put it over 100. To change a percent to a decimal, divide it by 100, which means move the decimal point two places to the left. 3i% = 31/100 = 0.31
20% The way to get percents from fractions is to turn the fraction to a decimal, and multiply the decimal by 100%. In this case, 1/5 = 0.2 0.2*100% = 20%
Surely percents can always be expressed as fractions or decimals, but percents are useful for comparing values- percents are essentially fractions all of the same denominator so they are easier to compare. Example: which is bigger 9/20 or 88/200 ? which is bigger 45% or 44% ? The percent question is easier to answer even though the numbers are the same.
Well, Decimal Point is like a another way of expressing a number like fractions and percents! Decimal point is a part of math and it looks something like this: 9.6 The dot represent for the decimal point.

They need to know about decimals, fractions, and percents because they need to know the exact measures of the things they are designing.

Percents are 100 times larger (and that is by definition!).
decimals fractions and percents are all alike because they show parts of 100, per 100(percent, cent representing for 100, century)
