Answer:
85%
Percentage solution with steps:
Step 1: We make the assumption that 80 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% = 80.
Step 4: In the same vein, x% = 68.
Step 5: This gives us a pair of simple equations:
100% = 80(1)
x% = 68(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left-hand side) of both equations have the same unit (%); we have
100%/x% = 80/68
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 68/80
__>x = 85%
Therefore, 68 is 85% of 80.
