a process to find the value between two percents

Question

describe a proccess that you can use to find a decimal whose value is between 31% and 32%

Answer 1

Add the two percentages together and divide by 200.

Add the percentages together:

31+32=63

Dividing by 200 is the same as dividing by 2 then dividing by 100
Divide 63 by 2:

31.5

To divide by 100, move the decimal point two places to the left:

.315

Finally, to avoid losing the decimal point, place 0 in front:

0.315

This decimal is between 31% and 32%
