Answer:
30
Explanation:
Change the divisor 2.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
750 ÷ 25 = 30.000
and therefore:
75 ÷ 2.5 = 30.000
Both calculated to 3 decimal places.
