The figures show 3 different fruits, a pineapple, a banana and 2 similar mangoes. The mass of the mango is
23 of the mass of the banana.
- Find the mass of the banana.
- Find the mass of the pineapple.
(a)
Mass of the mango = 2 u
Mass of the banana = 3 u
(Weighing scale on the right)
10 intervals → 1000 g
1 interval → 1000 ÷ 10 = 100 g
Mass of 2 mangoes
= 1000 + 4 x 100
= 1000 + 400
= 1400 g
Mass of 1 mango
= 1400 ÷ 2
= 700 g
(Weighing scale on the left)
1 kg = 1000 g
2 kg = 2000 g
10 intervals → 1 kg = 1000 g
1 interval → 1000 ÷ 10 = 100 g
Mass of the banana and the pineapple
= 2000 + 7 x 100
= 2000 + 700
= 2700 g
2 u = 700
1 u = 700 ÷ 2 = 350
Mass of the banana
= 3 u
= 3 x 350
= 1050 g
(b)
Mass of the pineapple
= 2700 - 1050
= 1650 g
Answer(s): (a) 1050 g; (b) 1650 g
