Question

Pencils come in packages of 10, Erasers come in packages of 5, Phillip wants to purchase the smallest number of pencils and erasers so that he will have exactly 1 eraser per pencil. How many packages of pencils and erasers should phillip buy

Answer 1

Answer:

1 pack of pencils. 2 pack of erasers

Step-by-step explanation:

this is a lcm based question. the reason why we use l is he asked the least set per item. so lcm of 5 and 10 is 10.that means 10 pencils are required.

10 pencils are in 1 package. so 1 pack of pencil is required. and 10 erasers means we require 2 packs of erasers to get 1 eraser per 1 pencil.

so answer is 1 pack of pencils and 2 packs of erasers
