- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
4 kg |
Milo |
275 g |
Biscuits |
365 g |
Tea |
400 g |
What is the difference between the total mass of milo collected and the total mass of tea collected? Give your answer in kg.
(a)
Number of packets of biscuits collected= 1 u
1 u = 30
Total number of packets of food items collected
= 3 u
= 3 x 30
= 90
Number of packets of rice collected
= 90 - 20 - 30 - 16
= 24
(b)
Total mass of milo collected
= 20 x 275
= 5500 g
Total mass of tea collected
= 16 x 400
= 6400 g
Difference between the total mass of milo and the total mass of tea collected
= 6400 - 5500
= 900 g
1000 g = 1 kg
900 g = 900 ÷ 1000 = 0.9 kg
Answer(s): (a) 24; (b) 0.9 kg
