$\frac{5}{6}$ of the lasagna is left

Step-by-step explanation:

Given:

Amount of lasagna Rico eats = 1/9

Amount of lasagna His friend eats = 1/18

To Find:

The amount lasagna is left =?

Solution:

Total lasagna ate by both Rico and his friend = Amount of lasagna Rico eats + Amount of lasagna His friend eats

Total lasagna ate by both Rico and his friend = $\frac{1}{9} + \frac{1}{18}$

Total lasagna ate by both Rico and his friend = $\frac{2}{19} + \frac{1}{18}$

Total lasagna ate by both Rico and his friend = $\frac{3}{18}$

Total lasagna ate by both Rico and his friend = $\frac{1}{6}$

The amount lasagna is left = 1 - Total lasagna ate by both Rico and his friend.

The amount lasagna is left = $1 - \frac{1}{6}$

The amount lasagna is left = $\frac{6-1}{6}$

The amount lasagna is left = $\frac{5}{6}$
