Write the problem "6 divided by 2" as fractions instead of whole numbers. You can also write the number 6 as 6/1, and the number 2 as 2/1. Therefore, "6 divided by 2" is the same as "6/1 divided by 2/1."
Invert the fraction in the denominator so 2/1 becomes 1/2.
Perform the inverse operation. The inverse of division is multiplication. So after inverting the fraction 2/1 to 1/2, multiply the problem instead of dividing. The problem becomes 6/1 times 1/2.
Multiply the fractions by multiplying the numerators and then multiplying the denominators: 6 times 1 equals 6, and 1 times 2 equals 2. The answer is 6/2, or the whole number 3.
Recall the rule for dividing two fractions. To divide 4/5 by 2/3, invert the fraction in the denominator (2/3) so it becomes 3/2.
Multiply the two fractions by multiplying the numerators and then multiplying the denominators: 4/5 divided by 2/3 equals 4/5 multiplied by 3/2.
Multiply the numerators: 4 times 3 equals 12. Multiply the denominators: 5 times 2 equals 10. The answer is 12/10.
Reduce the fraction 12/10 to its lowest terms by finding a whole number other than 1 that you can divide into both the numerator and denominator. You can divide the number 2 evenly into both the numerator and the denominator: 12/2 equals 6, and 10/2 equals 5. So the answer is 6/5, which you can further reduce to 1 1/5.
