Study the picture. Answer the following.
- What is the mass of the pear in g?
- How much heavier is the pear than the apple in g?
(a)
1 kg = 1000 g
Increment in mass marked by each line of the weighing scale
= 200 ÷ 10
= 20 g
6th line of the second weighing scale after 0 g
= 6 x 20
= 120 g
Mass of the apple = 120 g
8th line of the first weighing scale after 400 g
= 400 + 8 x 20
= 400 + 160
= 560 g
Mass of the pear and the apple = 560 g
Mass of the pear
= 560 - 120
= 440 g
(b)
Mass of the pear heavier than the apple
= 440 - 120
= 320 g
Answer(s): (a) 440 g; (b) 320 g
