bagirrra123 [75]

Jake added $\frac{37}{40}$ cup of toppings to his sundae.

Step-by-step explanation:

Given,

Amount of sunflower seeds added = $\frac{1}{8}\ of\ a\ cup$

Amount of banana chips added = $\frac{4}{5}\ of\ cup$

Total = Amount of sunflower seeds + Amount of banana chips

Total = $\frac{1}{8}+\frac{4}{5}$

Taking LCM = 40

$Total = \frac{5+32}{40}\\\\Total = \frac{37}{40}$

Jake added $\frac{37}{40}$ cup of toppings to his sundae.
