A shopkeeper keeps his stock of flour in 45-kg bags. He has 3 such bags to be packed into smaller packets weighing 7 kg and 1 kg. He wants to have the same number of 7-kg packets and 1-kg packets.
- How many packets of flour does he pack altogether?
- How much flour is left over?
(a)
Total mass of flour
= 3 x 45
= 135 kg
Mass of one set of 1 1-kg packet and 1 7-kg packet
= 1 + 7
= 8 kg
Number of sets
= 135 ÷ 8
= 16 r 7
Number of packets of flour
= 2 x 16
= 32
(b)
Mass of flour left over = 7 kg
Answer(s): (a) 32; (b) 7 kg
