Mass of each packet |
Flour |
8 kg |
Cereals |
250 g |
Oats |
475 g |
Pasta |
400 g |
What is the difference between the total mass of cereals collected and the total mass of pasta collected? Give your answer in kg.
(a)
Number of packets of oats collected= 1 u
1 u = 32
Total number of packets of food items collected
= 3 u
= 3 x 32
= 96
Number of packets of flour collected
= 96 - 28 - 32 - 22
= 14
(b)
Total mass of cereals collected
= 28 x 250
= 7000 g
Total mass of pasta collected
= 22 x 400
= 8800 g
Difference between the total mass of cereals and the total mass of pasta collected
= 8800 - 7000
= 1800 g
1000 g = 1 kg
1800 g = 1800 ÷ 1000 = 1.8 kg
Answer(s): (a) 14; (b) 1.8 kg
