Question

Solve the percent problem for the unknown base.
38% of what length is 19 cm?

Answer 1

19 divided by 38

times 100

when you do something times 38 = 19
that something is the one percent value
so 38 X = 19
X = 19/38
and then 100 times one percent is the 100 percent value

Answer 2

Set up a proportion: 38/100=x/19. Cross multiply and solve for x.
