How do you divide a decimal by a whole number?: Divide normally using long division, then bring the decimal point straight up into the quotient.
How do you divide by a decimal?: Multiply both the dividend and divisor by a power of 10 to make the divisor a whole number, then divide.
Dividend: The number being divided (goes inside the division bracket).
Divisor: The number you divide by (goes outside the division bracket).
Quotient: The answer to a division problem.
6.4 ÷ 8 = ?: 0.8 (64 ÷ 8 = 8, then 1 decimal place → 0.8)
4.5 ÷ 0.5 = ?: 9 (multiply both by 10: 45 ÷ 5 = 9)
0.72 ÷ 0.9 = ?: 0.8 (multiply both by 10: 7.2 ÷ 9 = 0.8)
3.0 ÷ 0.06 = ?: 50 (multiply both by 100: 300 ÷ 6 = 50)
Check your division answer by...: Multiplying the quotient by the divisor — you should get the dividend.
