Answer:
D = 41%
Step-by-step explanation:
To calculate what percentage of the number 32 is 13, we must create a proportion from which we can easily determine the value we are looking for.
First we create two simple equations with data that we know. We know from homework that 32 equals 100%, so we can save as 32 = 100%
The value we are looking for can be called x.
We know that x% is equal to 13 of the output value, so we can write it as x% = 13.
So we have two simple equations:
1) 100% = 32
2) x% = 13
When we compare these two equations, we get:
(100%) / (x%) = 32/13
Now we just have to solve the simple equation.
We calculate that percentage of 32 is 13
(100%) / (x%) = 32/13
(100 / x) * x = (32/13) * x
100 = 2.4615384615385 * x
100 / 2.4615384615385 = x
40.625 = x
x = 40.625
Solution:
13 equals 40.625 percent of 32
