Answer:

1. 5 min : 3 min

2. 10 cm : 7 cm

3. 9 sec : 10 sec

Explanation:

1. Since 60 minutes = 1 hour

Thus;

100 minutes : 60 minutes

10 minutes : 6 minutes

5 minutes : 3 minutes

The simplest form = (5:3) minutes

2. 100 cm = 1 m,

⇒ 15 m = 15 x 100 cm = 1500 cm

Thus;

1500 cm : 1050 cm

150 cm : 105 cm

30 cm : 21 cm

10 cm : 7 cm

The simplest form = (10:7) cm

3. 60 seconds = 1 minute

⇒ 9 minutes = 9 x 60

= 540 seconds

Thus;

540 seconds : 600 seconds

54 seconds : 60 seconds

9 seconds : 10 seconds

The simplest form = (9:10) seconds

4. A common fraction is one that has the same value on each side of an expression or equation.
