Catties, feet and imperial units worksheet: Answers and working

1. 79
1 catty = 16 taels. Change 4 catties into taels first, then add 15.
1 catty = 16 taels: 4 × 16 = 64, 64 + 15 = 79.
2. 77
1 foot = 12 inches. Change 6 feet into inches first, then add 5.
1 foot = 12 inches: 6 × 12 = 72, 72 + 5 = 77.
3. 91.44
Each inch is 2.54 cm, so 36 inches is 36 lots of 2.54.
36 × 2.54 = 91.44.
4. 3525
Do them apart: first 5 catties in grams, then 14 taels in grams.
5 × 600 = 3000, 14 × 37.5 = 525, 3000 + 525 = 3525.
5. 24
How many lots of 5 miles is 15 miles? Work out 15 ÷ 5 first.
15 ÷ 5 = 3, so it is 3 times 5 miles: 8 × 3 = 24.
6. 45
How many lots of 8 km is 72 km? Work out 72 ÷ 8 first.
72 ÷ 8 = 9, so it is 9 times 8 km: 5 × 9 = 45.
7. 59.2
Each mile is about 1.6 km, so 37 miles is 37 lots of 1.6.
37 × 1.6 = 59.2.
8. 6.27
Each pint is about 0.57 litres, so 11 pints is 11 lots of 0.57.
11 × 0.57 = 6.27.

9. C. 4 catties
Different units can't be compared directly. Change 4 catties, 1 kg and 4 pounds into grams.
All in grams: 2400, 1000, 1816 and 1600; the heaviest is 2400 g.
10. True
Change both into grams: 9 pounds is about 9 × 454 g, and 3 kg is 3 × 1000 g.
9 pounds is about 9 × 454 = 4086 g, and 3 kg is 3000 g.
11. B. 9 miles
Change them all into metres: 1 mile is about 1600 m and 1 km is 1000 m.
All in metres: 1 mile is about 1600 m. Of 14400, 3000, 4500 and 9600, the longest is 14400 m.
12. False
Change 5 pints into litres first, 5 × 0.57, then compare with 5 litres.
5 pints is about 5 × 0.57 = 2.85 litres; compare with 5 litres.

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

13. 170 cm
Change 5 feet 7 inches all into inches first (1 foot = 12 inches), then multiply by 2.54.
5 ft 7 in = 67 inches; 67 × 2.54 = 170.18, about 170 cm.
14. 406 dollars
Change 10 taels into catties first, 1016 of a catty, to see how many catties the fish weighs.
10 taels = 1016 catty, so it weighs 3.625 catties: 112 × 3.625 = 406.
15. 1616 g
Change 4 pounds into grams first, 4 × 454, then subtract the 200 g used.
4 pounds is about 4 × 454 = 1816 g; 1816 − 200 = 1616.
16. 4.8 km
Each mile is about 1.6 km, so 3 miles is 3 lots of 1.6.
3 × 1.6 = 4.8 km.
17. 54 litres
Each gallon is about 4.5 litres, so 12 gallons is 12 lots of 4.5.
12 × 4.5 = 54 litres.
18. 48 km
How many lots of 5 miles is 30 miles? Work out 30 ÷ 5 first.
30 miles is 6 times 5 miles: 8 × 6 = 48 km.
