Answer 1

Step-by-step explanation:

• Add both time taken yo complete

¾+⅞

= 13/8hour

Answer 2

Given,

Mikey worked for mathematics homework $\[ = \frac{3}{4}hours\]$

Mikey worked for science homework $\[ = \frac{7}{8}hours\]$

Solution,

Calculate the time that Mikey spend in her homework.

$\[ = \frac{3}{4} + \frac{7}{8}\]$

$\[ = \frac{{3 \times 2}}{{4 \times 2}} + \frac{7}{8}\]$

$\[ = \frac{6}{8} + \frac{7}{8}\]$

$\[ = \frac{{13}}{8}hours\]$

Hence Mikey spend $\[\frac{{13}}{8}hours\]$ on her homework.
