Zara baked 243 biscuits. She ate 3
f of them and divided the remainder equally among her 6 friends.
- Find the number of biscuits each of her friends received in terms of f?
- If f = 11, how many biscuits did each of her friends receive?
(a)
Number of biscuits left after Zara ate = 243 - 3
fNumber of biscuits that each of her friends received =
243 - 3f6 (b)
Number of biscuits that each of her friends received
= (243 - (3 x 11)) ÷ 6
= (243 - 33) ÷ 6
= 210 ÷ 6
= 35
Answer(s): (a)
