Answer:
100.
Step-by-step explanation:
The percentage of children's watches = 100 - 20 - 40 = 100-60
= 40%.
40% = 0.40 as a decimal fraction.
So the number of children's watches
= 0.40 * 250
= 100.

Rise over run or change in y over change in x
The letter x means to find the value or any letter in the alphabet
So what you would do is you would divide the top number (numerator) by the bottom number (denominator) Like you would normally. So take 3/10 for example you would punch into a calculator 3 divided by 10 or do the work which would be
0.3
and that is how you convert a fraction into a decimal with a denominator of 10
I hope that this helped you. (:
