**Negative numbers**

**Negative of a numbers, **

**Reciprocal of rational numbers,**

The multiplicative inverse of any rational number

**Example**

The reciprocal of 4/5 is 5/4.

**Distributivity of multiplication over addition for rational numbers,**

This shows that for all rational numbers p, q and r

1. p(q + r) = pq + pr

2. p(q – r) = pq – pr

**Example**

Check the distributive property of the three rational numbers 4/7,-( 2)/3 and 1/2.

**Solution**

Let’s find the value of

This shows that

**Distributivity of multiplication over subtraction for rational numbers**

The distributive property of rational numbers states that if any expression with three rational numbers A, B, and C is given in form A (B + C), then it can be solved as A × (B + C) = AB + AC. This applies to subtraction also which means A (B - C) = AB - AC. This means operand A is distributed between the other two operands, i.e., B and C. This property is also known as the distributive property of multiplication over addition or subtraction.
