Study the picture. Answer the following.
- What is the mass of the grapes in g?
- How much heavier is the grapes 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
1st line of the first weighing scale after 400 g
= 400 + 1 x 20
= 400 + 20
= 420 g
Mass of the grapes and the orange = 420 g
Mass of the grapes
= 420 - 100
= 320 g
(b)
Mass of the grapes heavier than the orange
= 320 - 100
= 220 g
Answer(s): (a) 320 g; (b) 220 g
