Answer:

272

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 340.

Step 2: We represent the unknown value with x or anything you'd like.

Step 3: From step 1 above, 340 in this case would equal 100% as a percent since that's the total value

Step 4: Just a reminder , x=80%

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

340= 100% (1)

x= 80% (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 (%); we have

340/x (340 over x) = 100%/80% (100% over 80%)

Step 7: Again, the reciprocal of both sides gives

x/340 (x over 340) = 80/100 (80 over 100)

x=272$

Therefore, 80% of 340 equals 272

Btw sorry if it's a bit confusing, but the answer is 272.
