45 g = __ mg
28 cm = __ mm
6.5 m = __ mm
2.7 m = __ cm
4 yd = __ in
7,658 g = __ kg
0.178 l = __ ml
4,300 m = __ km

Explanation:

Step1: Recall gram - milligram conversion

1 g = 1000 mg, so 45 g = 45×1000 mg = 45000 mg.

Step2: Recall centimeter - millimeter conversion

1 cm = 10 mm, so 28 cm = 28×10 mm = 280 mm.

Step3: Recall meter - millimeter conversion

1 m = 1000 mm, so 6.5 m = 6.5×1000 mm = 6500 mm.

Step4: Recall meter - centimeter conversion

1 m = 100 cm, so 2.7 m = 2.7×100 cm = 270 cm.

Step5: Recall yard - inch conversion

1 yd = 36 in, so 4 yd = 4×36 in = 144 in.

Step6: Recall gram - kilogram conversion

1 kg = 1000 g, so 7658 g = 7658÷1000 kg = 7.658 kg.

Step7: Recall liter - milliliter conversion

1 L = 1000 mL, so 0.178 L = 0.178×1000 mL = 178 mL.

Step8: Recall meter - kilometer conversion

1 km = 1000 m, so 4300 m = 4300÷1000 km = 4.3 km.

Answer:

45 g = 45000 mg
28 cm = 280 mm
6.5 m = 6500 mm
2.7 m = 270 cm
4 yd = 144 in
7658 g = 7.658 kg
0.178 L = 178 mL
4300 m = 4.3 km
