Question

1. 7870 ml to l
2. 6.42 m to mm
3. 1850 cm to m
4. 11.4 km to m
5. 3 m to mm
6. 25 mg to g
7. 74 cm to mm*
8. 835 mg to kg*

Explanation:

Step1: Recall conversion factor for mL to L

1 L = 1000 mL, so to convert mL to L, divide by 1000.
$7870\div1000 = 7.87$ L

Step2: Recall conversion factor for m to mm

1 m = 1000 mm, so to convert m to mm, multiply by 1000.
$6.42\times1000=6420$ mm

Step3: Recall conversion factor for cm to m

1 m = 100 cm, so to convert cm to m, divide by 100.
$1850\div100 = 18.5$ m

Step4: Recall conversion factor for km to m

1 km = 1000 m, so to convert km to m, multiply by 1000.
$11.4\times1000 = 11400$ m

Step5: Recall conversion factor for m to mm

1 m = 1000 mm, so to convert m to mm, multiply by 1000.
$3\times1000=3000$ mm

Step6: Recall conversion factor for Mg to g

1 Mg = 1000000 g, so to convert Mg to g, multiply by 1000000.
$25\times1000000 = 25000000$ g

Step7: Recall conversion factor for cm to mm

1 cm = 10 mm, so to convert cm to mm, multiply by 10.
$74\times10 = 740$ mm

Step8: Recall conversion factor for mg to kg

1 kg = 1000000 mg, so to convert mg to kg, divide by 1000000.
$835\div1000000=0.000835$ kg

Answer:

1. 7.87 L
2. 6420 mm
3. 18.5 m
4. 11400 m
5. 3000 mm
6. 25000000 g
7. 740 mm
8. 0.000835 kg
