Study the diagrams. Answer the following.
- What is the mass of the jack fruit in kg and g?
- What is the mass of the papaya in g?
- What is the mass of the bunch of apple in g?
(a)
1 kg = 1000 g
2 kg = 2000 g
Every 1 line of the first weighing scale → 2000 ÷ 20 = 100 g
2nd line of the first weighing scale after 2 kg
= 2000 + 2 x 100
= 2000 + 200
= 2200 g
Mass of the jack fruit = 2200 g
2200 g = 2 kg 200 g
(b)
Every 1 line of the second weighing scale → 100 ÷ 10 = 10 g
5
th line of the second weighing scale after 200 g
= 200 + 5 x 10
= 200 + 50
= 250 g
Mass of the papaya = 250 g
(c)
5
th line of the third weighing scale after 100 g
= 100 + 5 x 10
= 100 + 50
= 50 g
Mass of the apple = 150 g
Answer(s): (a) 2 kg 200 g; (b) 250 g; (c) 150 g
