Question

2)Whitney is shopping for party supplies. She finds a package of 10 plates, 16 napkins, and a package of 8 cups. What is the least number of packages of plates, napkins, and cups so that she has the same number of each? Write answer in sentence form.

Answer 1

$10=2\cdot5\\16=2^4\\8=2^3\\\\\text{lcm}(10,16,8)=2^4\cdot5=80$

80/10=8 packages of plates

80/16=5 packages of napkins

80/8=10 packages of cups
