Question

Solve using suitable property -2/3 x 5/7 x -9/16 x 14/25

Answer 1

`(3)/(20)`

Explanation:

We need to solve the given expression i.e.

`(-2)/(3)* (5)/(7)* (-9)/(16)* (14)/(25)`

It can be calculated by simplifying such that,

25 = 5 × 5

16 = 8 × 2

14 = 7× 2

9 = 3 × 3

If we use all the values,

we get,

`(-2)/(3)* (5)/(7)* (-9)/(16)* (14)/(25)=(3)/(20)`

So, the value of the above expression is equal to
`(3)/(20)`.
