2 kg |
Dried Nuts |
290 g |
Dried Fruits |
280 g |
Milo |
200 g |
What is the difference between the total mass of dried fruits collected and the total mass of rice collected? Give your answer in kg.
(a)
Number of packets of dried nuts collected = 1 u
1 u = 40
Total number of packets of food items collected
= 3 u
= 3 x 40
= 120
Number of packets of milo collected
= 120 - 30 - 40 - 38
= 12
(b)
1 kg = 1000 g
2 kg = 2 x 1000 = 2000
Total mass of rice collected
= 30 x 2000
= 60000 g
Total mass of dried fruits collected
= 38 x 280
= 10640 g
Difference between the total mass of dried fruits and the total mass of rice collected
= 60000 - 10640
= 49360 g
1000 g = 1 kg
49360 g = 49360 ÷ 1000 = 49.36 kg
Answer(s): (a) 12; (b) 49.36 kg
