Name the property of multiplication illustrated by the following statements:
(i) `(-15)/(8)xx(-12)/(7) = (-12)/(7)xx (-15)/(8)`
(ii) `((-2)/(3) xx (7)/(9)) xx (-9)/(5) = (-2)/(3)xx ((7)/(9)xx (-9)/(5))`
(iii) `(-3)/(4) xx ((-5)/(6)+(7)/(8))= ((-3)/(4)xx (-5)/(6))+((-3)/(4)xx (7)/(8))`
(iv) `(-16)/(9) xx 1 = 1 xx (-16)/(9) = (-16)/(9)`
(v) `(-11)/(15)xx (15)/(-11) =(15)/(-11)xx (-11)/(15) = 1`
(vi) `(-7)/(5) xx 0 =0`

The correct Answer is:
To solve the question, we will identify the property of multiplication illustrated by each of the given statements step by step. ### Step-by-Step Solution: 1. **Statement (i)**: \[ \frac{-15}{8} \times \frac{-12}{7} = \frac{-12}{7} \times \frac{-15}{8} \] - This statement shows that the order of multiplication does not change the product. - **Property**: **Commutative Law of Multiplication**. 2. **Statement (ii)**: \[ \left(\frac{-2}{3} \times \frac{7}{9}\right) \times \frac{-9}{5} = \frac{-2}{3} \times \left(\frac{7}{9} \times \frac{-9}{5}\right) \] - This statement shows that when multiplying three numbers, the way in which the numbers are grouped does not change the product. - **Property**: **Associative Law of Multiplication**. 3. **Statement (iii)**: \[ \frac{-3}{4} \times \left(\frac{-5}{6} + \frac{7}{8}\right) = \left(\frac{-3}{4} \times \frac{-5}{6}\right) + \left(\frac{-3}{4} \times \frac{7}{8}\right) \] - This statement shows that multiplication distributes over addition. - **Property**: **Distributive Property**. 4. **Statement (iv)**: \[ \frac{-16}{9} \times 1 = 1 \times \frac{-16}{9} = \frac{-16}{9} \] - This statement shows that multiplying any number by 1 gives the same number. - **Property**: **Multiplicative Identity Property**. 5. **Statement (v)**: \[ \frac{-11}{15} \times \frac{15}{-11} = \frac{15}{-11} \times \frac{-11}{15} = 1 \] - This statement shows that a number multiplied by its reciprocal equals 1. - **Property**: **Multiplicative Inverse Property**. 6. **Statement (vi)**: \[ \frac{-7}{5} \times 0 = 0 \] - This statement shows that any number multiplied by 0 results in 0. - **Property**: **Multiplicative Property of Zero**. ### Summary of Properties: - (i) Commutative Law of Multiplication - (ii) Associative Law of Multiplication - (iii) Distributive Property - (iv) Multiplicative Identity Property - (v) Multiplicative Inverse Property - (vi) Multiplicative Property of Zero
