Answer:
76
We make the assumption that 85 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that 100% = 85
54.91
Step-by-step explanation:
64.6/x=100/85
(64.6/x)*x=(100/85)*x
64.6=1.17*x (divide both sides of the equation by 1.17 to get x)
54.91=x
x=54.91
now we have 85% of 64.6= 54.91
9:15
