PSLE Erika and Nicole each had a plate of dough of the same mass for making scones. The same mass of dough was used for each scone. Erika made 33 scones and had 495 g of dough left. Nicole made 17 scones and had 1.055 kg of dough left.
- What was the mass of dough needed for each scone?
- With the remaining dough from both girls, how many more such scones can be made at most?
(a)
Difference between the number of scones made by Erika and Nicole
= 33 - 17
= 16
1 kg = 1000 g
1.055 kg = 1.055 x 1000 = 1055 g
Difference between the remaining dough left by Nicole and Erika
= 1055 - 495
= 560 g
Mass of 16 scones = 560 g
Mass of 1 scone
= 560 ÷ 16
= 35 g
(b)
Total remaining dough left
= 1055 + 495
= 1550 g
Sets of 35 g
= 1550 ÷ 35
= 44 r 10
Number of scones = 44
Answer(s): (a) 35 g; (b) 44
