Answer:
D. 55%
Step-by-step 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
[tex]\frac{100}{x} = \frac{280}{154}[/tex]
( 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
[tex]\frac{x}{100} =\frac{154}{280}[/tex]
( Again the 100 and X both have % at the end of them the equation thing wasn't allowing that though)
[tex]- > x=55%[/tex]%
Therefore, 154 is 55% of 280.
Hope this helps :)
