For every 24meals Momoka prepared for customers last night, she prepared 2 meals for employees. Momoka prepared 156 meals.
Olenka [21]

Answer:

144 meals for customers and 12 meals for employees.

Step-by-step explanation:

156/24=6.5

6 x 24 =144

156-144=12

It adds up to be simple numbers, if it didn't it would make sense. For example, she wouldn't serve 6 and a <u>half</u> people. She would serve either 6 people or 7 people. She wouldn't serve 11.3973043 meals. She would serve either 11 meals or 12 meals.
