Try dividing the surface area of the wall by 6.
#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply

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
