You're on a roll — Step 1: Solve Question 1. To find the number of cm, use the conversion 1 metre = 100 cm. a) (1)/(2) of 1 metre (1)/(2) × 100 cm = 50 cm The answer is 50 cm. b) (1)/(4) of 1 metre (1)/(4) × 100 cm = 25 cm The answer is 25 cm. c) (1)/(5) of 1 metre (1)/(5) × 100 cm = 20 cm The answer is 20 cm. d) (7)/(10) of 1 metre (7)/(10) × 100 cm = 7 × 10 cm = 70 cm The answer is 70 cm. e) (1)/(8) of 2 metres First, convert 2 metres to cm: 2 × 100 cm = 200 cm. (1)/(8) × 200 cm = 25 cm The answer is 25 cm. f) (3)/(5) of 1 metre (3)/(5) × 100 cm = 3 × 20 cm = 60 cm The answer is 60 cm. Step 2: Solve Question 2. To find the number of minutes, use the conversion 1 hour = 60 minutes. a) (1)/(5) hour (1)/(5) × 60 minutes = 12 minutes The answer is 12 minutes. b) (1)/(6) hour (1)/(6) × 60 minutes = 10 minutes The answer is 10 minutes. c) (1)/(10) hour (1)/(10) × 60 minutes = 6 minutes The answer is 6 minutes. d) (2)/(3) hour (2)/(3) × 60 minutes = 2 × 20 minutes = 40 minutes The answer is 40 minutes. e) (1)/(20) of 2 hours First, convert 2 hours to minutes: 2 × 60 minutes = 120 minutes. (1)/(20) × 120 minutes = 6 minutes The answer is 6 minutes. f) (2)/(15) of 2 hours First, convert 2 hours to minutes: 2 × 60 minutes = 120 minutes. (2)/(15) × 120 minutes = 2 × 8 minutes = 16 minutes The answer is 16 minutes. What's next?
