- The table shows the mass of each packet of food.

Rice |
6 kg |
Milo |
460 g |
Oats |
490 g |
Noodles |
200 g |
What is the difference between the total mass of noodles collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 38
Total number of packets of food items collected
= 3 u
= 3 x 38
= 114
Number of packets of oats collected
= 114 - 38 - 34 - 18
= 24
(b)
Total mass of noodles collected
= 18 x 200
= 3600 g
Total mass of milo collected
= 34 x 460
= 15640 g
Difference in mass between the total mass of noodles and the total mass of milo collected
= 15640 - 3600
= 12040 g
1000 g = 1 kg
12040 g = 12040 ÷ 1000 = 12.04 kg
Answer(s): (a) 24; (b) 12.04 kg
