Question

Make the following metric measurement conversion in order to solve the riddle. What does Amaya say about her friend who is really into measurement?
1.) 38 mm = __________ m

2.) 24 dm = __________ mm

3.) 10 cm = __________ mm

4.) 81 cm = __________ m

5.) 3, 400 g = __________ kg

6.) 64 mm = __________ cm

Answer 1

Step-by-step explanation:

38mm = 38m

28dm = 2.4m

10cm = 0.1mm

81cm = 0.81m

3,400g = 3.4kg

64mm = 6.4cm

Answer 2

Answer:

1. 38mm = 0.038m
2. 24dm = 2400mm
3. 10cm = 100mm
4. 81cm = 0.81m
5. 3400g = 3.4kg
6. 64mm = 6.4cm

Step-by-step explanation:

Recall the concepts:

1000mm = 1m

1dm =  100mm

10mm = 1cm  

100cm = 1m

1000g = 1kg

10mm = 1cm

1) 38 mm = __________ m

Since 1000mm = 1m

1mm = $\frac{1}{1000}$m

38mm = $\frac{1}{1000}$ × 38 = 0.038m

38mm = 0.038m

2)24 dm = __________ mm

Since 1dm =  100mm

24dm = 24×100

24dm = 2400mm

3)  10 cm = __________ mm

Since 1cm = 10mm

10cm = 10×10 = 100mm

10cm = 100mm

4)81 cm = __________ m

Since 100cm =  1m

1cm = $\frac{1}{100}$m

81cm = $\frac{1}{100}$×81 = $\frac{81}{100}$m = 0.81m

81cm = 0.81m

5)3, 400 g = __________ kg

Since 1000g = 1kg

1g = $\frac{1}{1000}$ kg

3400g =  $\frac{1}{1000}$×3400kg = 3.4kg

3400g = 3.4kg

6)64 mm = __________ cm

Since 10mm = 1cm

1mm = $\frac{1}{10}$cm

64mm = 64×$\frac{1}{10}$ = 6.4cm

64mm = 6.4cm
