Question

What is 40% of 280 step by step?

Answer 1

40% of 280=

40/100 × 280=

112

Answer 2

Step 1: Our output value is 280.

Step 2: We represent the unknown value with x

Step 3: From step 1 above,280 = 100 percent

Step 4: Similarly, x = 40 percent

Step 5: This results in a pair of simple equations:

280 = 100 percent (1)

x = 40 percent (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (percent); we have

280/x = 100percent/40percent

Step 7: Again, the reciprocal of both sides gives

x/280 = 40/100

>x = 112​

Therefore, 40percent of 280 is 112
