Answer:
[tex]\frac{5}{6}[/tex] 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 = [tex]\frac{1}{9} + \frac{1}{18}[/tex]
Total lasagna ate by both Rico and his friend = [tex]\frac{2}{19} + \frac{1}{18}[/tex]
Total lasagna ate by both Rico and his friend = [tex]\frac{3}{18} [/tex]
Total lasagna ate by both Rico and his friend = [tex]\frac{1}{6} [/tex]
The amount lasagna is left = 1 - Total lasagna ate by both Rico and his friend.
The amount lasagna is left = [tex]1 - \frac{1}{6}[/tex]
The amount lasagna is left =[tex]\frac{6-1}{6}[/tex]
The amount lasagna is left =[tex]\frac{5}{6}[/tex]
