Question

Neville is making a 180-piece jigsaw puzzle that is 4 times as many pieces as Luna's.

Answer 1

Answer:

n = 30 pieces

Step-by-step explanation:

Firstly calculate the number of pieces that Luna's puzzle has....,

;180 ÷ 4 = 45 pieces

Hence if Luna has used 15 pieces...then the number of pieces left,

; 45 - 15 = n

;Hence..., n = 30 pieces
