Answer:0.4375
Step-by-step explanation:
To solve the problem, we start by labeling 1/2 of 7/8 like this:
N1/D1 of N2/D2
Then we use this fraction of a fraction formula to solve the problem:
(N1 x N2) / (D1 x D2)
When we enter 1/2 of 7/8 into the formula, we get:
(1 x 7) / (2 x 8) = 7/16
Therefore, the answer to 1/2 of 7/8 in its lowest form is:
1/2 of 7/8 = 7/16
About 11% - I first subtracted 250 from 282, to get 32. I then did 32/282 to get .11.... You round that out to about 11%
