One serving of oatmeal provides 16% of the fiber, f, a person needs each day. You must get the remaining 21 g of fiber from other sources. How many grams of fiber do you need each day? Show an equation including using f as the variable, and solve plz show work

F=fibre

Total of fibre = 100%

100% = 16% = 21g

100% - 16% = 84%

21 grams = 84%

1% = 21 {divided by} 84

1% = 0.25g

16% = 1% {times} 16

16% = 0.25 {times} 16

16% = 4

100% = 16% + 84%

100% = 4 + 21

100% = 25

You need 25 grams of fibre each day.
