- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Flour |
7 kg |
Biscuits |
490 g |
Milo |
360 g |
Oats |
200 g |
What is the difference between the total mass of oats collected and the total mass of biscuits collected? Give your answer in kg.
(a)
Number of packets of flour collected = 1 u
1 u = 26
Total number of packets of food items collected
= 4 u
= 4 x 26
= 104
Number of packets of milo collected
= 104 - 26 - 36 - 30
= 12
(b)
Total mass of oats collected
= 30 x 200
= 6000 g
Total mass of biscuits collected
= 36 x 490
= 17640 g
Difference in mass between the total mass of oats and the total mass of biscuits collected
= 17640 - 6000
= 11640 g
1000 g = 1 kg
11640 g = 11640 ÷ 1000 = 11.64 kg
Answer(s): (a) 12; (b) 11.64 kg
