Answer:
28%
Explanation:
Percentage solution with steps:
Step 1: We make the assumption that 4.5 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% = 4.5
Step 4: In the same order, x% = 1.26
Step 5: This gives us a pair of simple equations:
100% = 4.5
x% = 1.26
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% = 4.5 / 1.26
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% / 100 = 1.26 / 4.5
x = 28 %
Therefore x = 28%
