Answer:
4.200
Step-by-step explanation:
Change the divisor 0.9 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:
37.8 ÷ 9 = 4.200
and therefore:
3.78 ÷ 0.9 = 4.200
Both calculated to 3 decimal places.
