- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
8 kg |
Oats |
490 g |
Lentils |
380 g |
Dried Fruits |
200 g |
What is the difference between the total mass of dried fruits collected and the total mass of oats collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 20
Total number of packets of food items collected
= 4 u
= 4 x 20
= 80
Number of packets of lentils collected
= 80 - 20 - 12 - 22
= 26
(b)
Total mass of dried fruits collected
= 22 x 200
= 4400 g
Total mass of oats collected
= 12 x 490
= 5880 g
Difference in mass between the total mass of dried fruits and the total mass of oats collected
= 5880 - 4400
= 1480 g
1000 g = 1 kg
1480 g = 1480 ÷ 1000 = 1.48 kg
Answer(s): (a) 26; (b) 1.48 kg
