Answer:
40%
Explanation:
Step 1: We make the assumption that 675 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\%=675.
Step 4: In the same vein, x\%=270.
Step 5: This gives us a pair of simple equations:
100\%=675(1).
x\%=270(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% = 675/270
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 270/675
x=40%
Therefore, 270 is 40% of 675
