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

Answer 1

Answer:

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

Step-by-step 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:

$\frac{X mm }{37cm} =\frac{10 mm}{1cm} \\x = 37 * 10 = 370$

2. Use proportions and cross-multiply:

$\frac{20 m}{X cm} =\frac{1 m}{100cm} \\x=20*100=2000$

3. Use proportions and cross-multiply:

$\frac{34in}{Xmm} =\frac{1in}{25.4mm} \\x=34*25.4=863.6$

4. Use proportions and cross-multiply:

$\frac{20m}{Xkm} =\frac{1m}{0.001km} \\x=20*0.001=0.02$

5. Use proportions and cross-multiply:

$\frac{29 km}{Xm}=\frac{1 km}{1000m} \\x=29*1000=29000$
