the answer

Answer 2

• We have to evaluate the above expression by using the given data.

        Given data:- $\frac{3}{7}\times(\frac{-2}{5} ).$

        To find:- Value of given expression=?

        Solution:-

• Multiplication is denoted by the symbol(x).

• 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.
2. Commutative property.
3. Associative property.
4. Distributive property.
5. Identity property.
6. Zero property.

       Therefore we get,

         $\frac{3}{7}\times(\frac{-2}{5} )\\\\\begin{array}{l}=\frac{3}{7} \times \frac{-2}{5} \\\\=\frac{3 \times-2}{7 \times 5} \\\\=-\frac{6}{35}\end{array}$

      Hence we will get the value is $=-\frac{6}{35} .$
