- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Flour |
8 kg |
Oats |
495 g |
Milo |
445 g |
Tea |
200 g |
What is the difference between the total mass of tea collected and the total mass of oats collected? Give your answer in kg.
(a)
Number of packets of flour collected = 1 u
1 u = 20
Total number of packets of food items collected
= 3 u
= 3 x 20
= 60
Number of packets of milo collected
= 60 - 20 - 14 - 10
= 16
(b)
Total mass of tea collected
= 10 x 200
= 2000 g
Total mass of oats collected
= 14 x 495
= 6930 g
Difference in mass between the total mass of tea and the total mass of oats collected
= 6930 - 2000
= 4930 g
1000 g = 1 kg
4930 g = 4930 ÷ 1000 = 4.93 kg
Answer(s): (a) 16; (b) 4.93 kg
