Answer:

Jason should buy 6 packages of pencils (60) and 5 packages of erasers (60).

Step-by-step explanation:

Here are two ways to find the LCM (Least Common Multiple) of two numbers:

 

[1] list all of the multiples and choose the least common number

of 10:   10  20  30  40  50  60  70  80  90  100

of 12:   12  24  36  48  60  72  84  96

 

[2] find a number that shares all the prime factors of the two numbers

(thus, is divisible by both of the numbers)

prime factors of 10:    2, 5

prime factors or 12:    2, 2, 3

LCM = 2*2*3*5 = 60
