Answer 1

D. 55%

Explanation:

Step 1: We make the assumption that 280 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% = 280

Step 4: In the same vein, x% = 154.

Step 5: This gives us a pair of simple equations: 100% = 280. x% = 154.

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) = (280)/(154)`

( The 100 and X both have % at the end of them the equation thing wasn't allowing that though)

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

`(x)/(100) =(154)/(280)`

( Again the 100 and X both have % at the end of them the equation thing wasn't allowing that though)

`- > x=55%`%

Therefore, 154 is 55% of 280.

Hope this helps :)
