Find 4/7 divided by 7/8

Reika [66]

If you divide a fraction by another fraction, this is equivalent to mupltiplying by its inverse:

so $\frac{4}{7}$ divided by $\frac{7}{8}$

is equivalent to

$\frac{4}{7}$ multiplied by by $\frac{7}{8}$

which is

$\frac{4}{7}* \frac{7}{8}= \frac{4*7}{7*8}= \frac{4}{8}= \frac{1}{2}$

so the answer is $\frac{1}{2}$ which is also 0.5
