Question

at the grocery store, apples were on sale for 30 cents each, pears were 20 cents each, and bananas were 12 cents each. if i want to spend the same amount of money on each kind of fruit, what is the least money i will spend in total?
$1.80
$1.20
$0.90
$0.60
$0.30

Explanation:

Step1: Find LCM of 30,20,12

Prime factors:
$30 = 2\times3\times5$
$20 = 2^2\times5$
$12 = 2^2\times3$
LCM is $2^2\times3\times5 = 60$ cents per fruit type.

Step2: Calculate total cost

3 fruit types, so total = $60\times3 = 180$ cents = $\$1.80$.

Answer:

$\$1.80$
