Grams and kilograms worksheet: Answers and working

1. 7 kg
Check the unit, then the gap between neighbouring numbers, and work out what each step between stands for.
The numbers go up 2 kg at a time, so the step between is 1 kg: 7 kg.
2. 1000
Each kilogram is 1000 g, so multiply 1 by 1000.
1 kg = 1000 g: 1 × 1000 = 1000.
3. 350 g
See how many steps each 100 g is split into, work out one step, then read the pointer.
Each 100 g has 2 steps of 50 g; the pointer is 1 step past the nearest number: 350 g.
4. 7000
Each kilogram is 1000 g, so multiply 7 by 1000.
1 kg = 1000 g: 7 × 1000 = 7000.

5. B. kg
A bag of rice is heavy. Which is the bigger unit for weight?
A bag of rice is heavy, so use kilograms: 5 kg.
6. D. g
An orange isn't very heavy. Which is the smaller unit for weight?
An orange isn't heavy, so use grams: about 250 g.
7. D. g
An orange isn't very heavy. Which is the smaller unit for weight?
An orange isn't heavy, so use grams: about 150 g.
8. C. kg
A bag of rice is heavy. Which is the bigger unit for weight?
A bag of rice is heavy, so use kilograms: 10 kg.
9. C. kg
A bag of rice is heavy. Which is the bigger unit for weight?
A bag of rice is heavy, so use kilograms: 1 kg.
10. False
The units differ: change 2 kg 570 g into grams first, then compare with 2870 g.
In grams: 2 kg 570 g = 2570 g, then compare with 2870 g.
11. False
The units differ: change 5 kg 830 g into grams first, then compare with 5870 g.
In grams: 5 kg 830 g = 5830 g, then compare with 5870 g.
12. False
The units differ: change 1 kg 170 g into grams first, then compare with 1470 g.
In grams: 1 kg 170 g = 1170 g, then compare with 1470 g.

Marking: 2 for the working, 1 for the answer, 1 for the sentence.

13. 2850 g
The units differ. Change 3 kg into grams first, then subtract the 150 g used.
3 kg = 3000 g; 3000 − 150 = 2850.
14. 1000, 1
Work out how many grams 5 apples weigh, then remember 1000 g is 1 kg.
200 × 5 = 1000 g; every 1000 g is 1 kg: 1 kg.
15. 500 g
Read what the scale shows first, then add the apple's 150 g.
The scale showed 350 g; 350 + 150 = 500.
16. 2000, 2
Work out how many grams 10 apples weigh, then remember 1000 g is 1 kg.
200 × 10 = 2000 g; every 1000 g is 1 kg: 2 kg.
17. 400 g
Read what the scale shows first, then add the apple's 300 g.
The scale showed 100 g; 100 + 300 = 400.
18. 2500 g
The units differ. Change 3 kg into grams first, then subtract the 500 g used.
3 kg = 3000 g; 3000 − 500 = 2500.
