Hi!
To solve this, we need to divide the fractions.
When dividing fractions, you multiply the first fraction by the reciprocal of the second fraction. The reciprocal is a flipped fraction. So the reciprocal of 1/2 is 2/1.
[tex] \frac{7}{8} * \frac{4}{1} [/tex]
[tex] \frac{28}{8} [/tex]
[tex] \frac{28}{8} [/tex] can be simplified to
[tex] \frac{7}{2} [/tex],
[tex]3 \frac{1}{2} [/tex],
or 3.5.
Hope this helps! :)
