both signify a part of a whole. percentages are based on 100 being 1 so 100% is 1 whole thing. 1 whole thing with decimals is 1.00. You can change from decimals to percentages by moving the decimal 2 places to the right and percentages to decimals by moving the decimal 2 places to the left.

divide the numerator by the denominator, and round to the nearest tenth or hundredth, whatever is best. Ex. 1 1/2 = 1.5 since 1 divided by 2 is .5, make the new number 1.5. if the number is 1 1/3, then the decimal would be 1.33333..... so then you would round it to the nearest tenth (1.3) or the nearest hundredth (1.33) and then put a repeating bar over the decimal.

1/10 * 2/10 = 2/100 = 0.02

A whole number is a number in which there is no decimal or fraction after the number or the number is a fraction or decimal. ex. ...-2, -1, 0, 1, 2...

.2

No. Whole numbers have only zeros after the decimal point (or the decimal point isn't shown at all). So; -3, -2, -1, 0, 1, 2, 3 ... etc are whole numbers

No. The number .205 is .005 smaller than .21 No. 0.21 is bigger.Note: To compare the decimal numbers,1) First compare the whole part.2) Then compare the fractional or decimal part. The numbers after the decimal point.3) Compare the tenth place, then compare the hundredth place and go on.Here 0 is the whole part.In the tenth place we have 2 in both the numbers. But in hundredth place we have 0 in the first number and 1 in the second number.So, the second number, 0.21 is bigger.Source: www.icoachmath.com

1/2 = .5 1/2 is a half a whole, and one whole number is 1. so half is 0.5

9 1/2 equals to 9.5 It is, a so called, 'terminating' decimal.

-If you mean what can .2 be divided by to get a whole number, then .1 works (.2/.1 = 2) -If you mean what can be divided by .2 to get a whole number, then 1 works (1/.2 = 5)
