Liam eats 3/4 of a pizza, and Sophia eats 5/8 of a pizza. Who ate more?
🔴 Liam’s Work:
"I compared 3 and 5. Since 5 is greater than 3, I think 5/8 is greater than 3/4."
Liam is wrong. 3/4 is more pizza than 5/8. The slices are bigger in the pizza cut into fourths so even if 3 is greater than 5, 3/4 is closer to one whole and 5/8 is closer to 1/2.
