1. 37cm= ___ mm 2. 20m=___cm 3. 34in=___mm 4. 20m=___km 5. 29km=___m

Answer 1

1. 370
2. 2000
3. 863.6
4. 0.02
5. 29000

Explanation:

• 1 cm = 10 mm
• 1 m = 100 cm
• 1 in = 25.4 mm
• 1 m = 0.001 km
• 1 km = 1000 m

1. Use proportions and cross-multiply:

`(X mm )/(37cm) =(10 mm)/(1cm) \\x = 37 * 10 = 370`

2. Use proportions and cross-multiply:

`(20 m)/(X cm) =(1 m)/(100cm) \\x=20*100=2000`

3. Use proportions and cross-multiply:

`(34in)/(Xmm) =(1in)/(25.4mm) \\x=34*25.4=863.6`

4. Use proportions and cross-multiply:

`(20m)/(Xkm) =(1m)/(0.001km) \\x=20*0.001=0.02`

5. Use proportions and cross-multiply:

`(29 km)/(Xm)=(1 km)/(1000m) \\x=29*1000=29000`
