LAST ONE! ASAP PLEASE

There are so many questions which one you don't know

Explanation:

Step 1: We make the assumption that 160 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%=160

Step 4: In the same vein, = x%=140.

Step 5: This gives us a pair of simple equations:

100%=160(1).

x%=140(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% = 160 / 140

Step 7: Taking the inverse (or reciprocal) of both sides yields

x% / 100% = 140 / 160

x% = 87.5%

therefore, 140 is 87.5% of 160
