Answer:
Norma ate [tex]\frac{9}{32}[/tex] of the leftover cake at her lunch.
Step-by-step explanation:
Norma had a leftover cake from her party = [tex]\frac{3}{8}[/tex]
She ate [tex]\frac{3}{4}[/tex]th of the leftover cake at the lunch.
Therefore, amount of cake she had at lunch = [tex]\frac{3}{8}\times \frac{3}{4}[/tex]
= [tex]\frac{9}{32}[/tex] of the leftover cake
Norma ate [tex]\frac{9}{32}[/tex] of the leftover cake at her lunch.
