Converting a larger unit to a smaller unit requires multiplication by the corresponding conversion factor and vice versa.

10^-3 = mm

1. 6.438m × 10^-3m = 0.006438 mm

2. 75.6m × 10-3m = 0.0756mm

Verified answer

Answer:

1m=1000mm

6.438m=6.438×1000mm

=6438mm

1m= 1000mm

75.6m=75.6×1000mm

=75600mm

Step-by-step explanation:

1m=1000mm

6.438m=6.438×1000mm

so the point is cut at the right side of the point there are 3 numbers and there are 3 zeros so 3 zeros are cutted.

6438×1=6438 mm Ans

1m=1000mm

75.6m=75.6×1000mm

so the point is cut at the right side of the point there are 1 numbers and there are 3 zeros so 1 zero is cutted.

756×100=75600mm Ans
