Divide and write in simplest form 4/7 divided by 1 1/7
IrinaVladis [17]

First, change the mixed fraction into improper fraction

1 1/7 = 7/7 + 1/7 = 8/7

(4/7)/(8/7)

To solve, flip the second fraction, and change the division into multiplication

(4/7)/(8/7) = (4/7) x (7/8)

Multiply, and simplify

(4/7) x (7/8) = 28/56, or 1/2

1/2 is your answer

hope this helps
