What is 5/6 divided by 1/7?

skelet666 [1.2K]

Answer:

5 $\frac{5}{6}$

Step-by-step explanation:

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. (Seven over one)

$\frac{5*7}{6*1} =\frac{35}{6}$

Now, we convert the fraction into a mixed fraction.

$\frac{35}{6}=5\frac{5}{6}$

The quotient of 5/6 and 1/7 is 5 5/6
