Study the picture. Answer the following.
- What is the mass of the banana in g?
- How much heavier is the banana than the orange in g?
(a)
1 kg = 1000 g
Increment in mass marked by each line of the weighing scale
= 200 ÷ 10
= 20 g
5th line of the second weighing scale after 0 g
= 5 x 20
= 100 g
Mass of the orange = 100 g
4th line of the first weighing scale after 400 g
= 400 + 4 x 20
= 400 + 80
= 480 g
Mass of the banana and the orange = 480 g
Mass of the banana
= 480 - 100
= 380 g
(b)
Mass of the banana heavier than the orange
= 380 - 100
= 280 g
Answer(s): (a) 380 g; (b) 280 g
