Answer:
64
Step-by-step explanation:
Your welcome
Determine your ratio. For example, assume your ratio is 9 out of 10.
Multiply
the numerator and the denominator by the same number. For example, 9
times 10 equals 90 and 10 times 10 equals 100, so the new ratio is 90
out of 100.
Divide the numerator and denominator of the
ratio by the same number to reduce the ratio. In the example, 90
divided by 50 equals 1.8 and 100 divided by 50 equals 2, so your ratio
is 1.8 out of 2.
The answer is 3
B+4=7
B=7-4
B=3
