Answer:
[tex]\frac{9}{20}[/tex]
Step-by-step explanation:
Given:
Elena ate 2/8 of a pizza.
Dylan ate 1/5 of a pizza.
Question asked:
How much of the pizza did they eat ?
Solution:
By simply adding.
Elena ate of a pizza. = [tex]\frac{2}{8}[/tex]
Dylan ate of a pizza = [tex]\frac{1}{5}[/tex]
Total of a pizza they ate = [tex]\frac{2}{8}[/tex] + [tex]\frac{1}{5}[/tex]
By taking LCM of 8 and 5 ; 40
[tex]\frac{10 + 8}{40} = \frac{18}{40} = \frac{9}{20}[/tex]
Thus, [tex]\frac{9}{20}[/tex] f the pizza they eat.
