To divide rational numbers, we can simply multiply the first number by the reciprocal of the second number.

To divide rational numbers, we can simplify the problem by multiplying the first number by the reciprocal of the second number. The reciprocal of a number is simply the number flipped upside down. For example, the reciprocal of 2 is 1/2, and the reciprocal of 1/2 is 2.

Here are some examples of how to divide rational numbers:

To divide 3/4 by 1/2, we can multiply 3/4 by the reciprocal of 1/2, which is 2/1. This gives us:

3/4 ÷ 1/2 = 3/4 × 2/1 = 6/4

Simplifying 6/4, we get 3/2.

To divide 5/6 by 2/3, we can multiply 5/6 by the reciprocal of 2/3, which is 3/2. This gives us:

5/6 ÷ 2/3 = 5/6 × 3/2 = 15/12

Simplifying 15/12, we get 5/4.

To divide -7/8 by -3/4, we can multiply -7/8 by the reciprocal of -3/4, which is -4/3. This gives us:

-7/8 ÷ -3/4 = -7/8 × -4/3 = 28/24

Simplifying 28/24, we get 7/6.
