Question

7 eights x 4 fifths is the math problem. I need to show work!

Answer 1

Solution:

Consider the following expression:

$\frac{7}{8}\text{ x }\frac{4}{5}$

By definition, to perform this operation we must multiply numerator with numerator and denominator with denominator, as follows:

$\frac{7}{8}\text{ x }\frac{4}{5}=\frac{7\text{ x 4}}{8\text{ x 5}}=\frac{28}{40}$

that is:

$\frac{7}{8}\text{ x }\frac{4}{5}=\frac{28}{40}$

Simplifying, this is equivalent to:

$\frac{7}{10}$

So that, we can conclude that the correct answer is:

$\frac{7}{10}$
