Question

could someone explain how to solve this?

Answer 1

Answer:

-$\frac{23}{56}$

Step-by-step explanation:

-$\frac{1}{8}$ - $\frac{2}{7}$

First, we need to make these fractions have the same denominator so that we can subtract them. We will multiply one fraction by the denominator of the other fraction over itself, because this is equal to 1 and does not actually change the value of the fraction.

-$\frac{1}{8}$ × $\frac{7}{7}$ = -$\frac{7}{56}$

-$\frac{2}{7}$ × $\frac{8}{8}$ = -$\frac{16}{56}$

Now we have:

-$\frac{7}{56}$ - $\frac{16}{56}$

-$\frac{23}{56}$ --- subtract the numerators
