1. express the following as ratios in simplest form

a) 2 hours to 300 minutes b) 5 km to 1 km 500 meters

a) 2:5

b) 10:3

Step-by-step explanation:

a) 2 hours = 60 min x 2 = 120 min

hence,

2 hours : 300 minutes

120 min : 300 min (divide both by 60)

2:5

b)

1km 500 m = 1000 + 500 = 1500m

5km = 5000m

hence,

5 km : 1 km 500 meters

5000 : 1500 (divide both sides by 500)

10:3

a) 2:5

b). 10:3.

Step-by-step explanation:

2 hours to 300 minutes

= 120 minutes to 300 minutes

Dividing both numbers by 60 we have

2 : 5.

b. 5 km to 1 km 500 m

= 5,000 m to 1500 m

Divide both numbers by 100:

= 50:15

= 10:3.
