Question

Find the product: 9/2 × (-7/4)​

Answer 1

To solve : $(\frac{9}{2}) \times (\frac{-7}{4} )$

solution:

• Multiplication is a process of repetitive addition of integers.
• Multiplication rules for integers :

1. if two negative integers are multiplied then the product obtained is positive integer. i.e.$(-) \times(-)=+$
2. If one negative and one positive integers are multiplied then the product obtained is negative integer. i.e. $(-) \times(+)=-$
3. If both positive integers are multiplied then the product obtained is positive integer. i.e. $(+) \times(+)=+$

• Therefore according to above rule we solve $(\frac{9}{2}) \times (\frac{-7}{4} )$

             $(\frac{9}{2}) \times (\frac{-7}{4})\\= \frac{-63}{8}$

Hence, $\frac{-63}{8}$ is the product.

Answer 2

• As per the data given in the question, we have to find the value of the expression.

              Given data:- $\frac{9}{2} \times(\frac{-7}{4} ).$

              To find:- Value of given expression=?

              Solution:-

• Multiplication is denoted by the symbol ($\times$).

• Multiplication is a method to get the product by multiplying two or more values.

• There are six properties of multiplication is given below:-

1. Closure property of multiplication.
2. Commutative property of multiplication.
3. Associative property of multiplication.
4. Distributive property of multiplication over addition.
5. Identity property of multiplication.
6. Zero property of multiplication.

     Therefore,

          $\frac{9}{2} \times(\frac{-7}{4} )\\=\frac{-63}{8} .$

   Hence we will get the product $\frac{-63}{8} .$
