Pasta |
410 g |
Lentils |
500 g |
What is the difference between the total mass of milo collected and the total mass of lentils collected? Give your answer in kg.
(a)
Number of packets of pasta collected= 1 u
1 u = 26
Total number of packets of food items collected
= 4 u
= 4 x 26
= 104
Number of packets of flour collected
= 104 - 34 - 26 - 32
= 12
(b)
Total mass of milo collected
= 34 x 335
= 11390 g
Total mass of lentils collected
= 32 x 500
= 16000 g
Difference between the total mass of milo and the total mass of lentils collected
= 16000 - 11390
= 4610 g
1000 g = 1 kg
4610 g = 4610 ÷ 1000 = 4.61 kg
Answer(s): (a) 12; (b) 4.61 kg
