Answer:
4.012 to 3 decimal places
Explanation:
The division of decimal numbers can be done easily by multiplying the numerator and denominator with a number whose power of 10 completely removes the decimal.
For 7.984 ÷ 1.99
= (7.984 × 10^3) ÷ (1.99 × 10^3)
= 7984/1990
= 4.012060302
≈ 4.012 to 3 decimal places
