What is the difference between the total mass of lentils collected and the total mass of pasta collected? Give your answer in kg.
(a)
Number of packets of milo collected= 1 u
1 u = 14
Total number of packets of food items collected
= 6 u
= 6 x 14
= 84
Number of packets of rice collected
= 84 - 18 - 14 - 36
= 16
(b)
Total mass of lentils collected
= 18 x 375
= 6750 g
Total mass of pasta collected
= 36 x 500
= 18000 g
Difference between the total mass of lentils and the total mass of pasta collected
= 18000 - 6750
= 11250 g
1000 g = 1 kg
11250 g = 11250 ÷ 1000 = 11.25 kg
Answer(s): (a) 16; (b) 11.25 kg
