Question

A cafeteria sold 80 frozen yogurts on Monday, and 55% of these were peach yogurt. How many peach yogurts were sold on Monday?

Answer 1

The key thing to note is that percentage means that number over 100. Thus 55% can be written as 55/100. This converts to the decimal 0.55. If we then multiply this by 80, we get 44.
44 peach yogurts were sold on Monday.

Answer 2

$55 \% \cdot80=\frac{55}{100}\cdot80=\frac{55}{10}\cdot8=\frac{55}{5}\cdot4=11\cdot4=44$

Answer: A cafeteria sold 44 peach yogurts on Monday.
