Answer:
0.708
Explanation:
Change the divisor 2.1 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:
14.88 ÷ 21 = 0.708
and therefore:
1.488 ÷ 2.1 = 0.708
Both calculated to 3 decimal places.
