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.
