Question

Hi, please solve this question...

1. The product of two rational numbers is-3/7. If one number is 2/5, what is the other number?​

Answer 1

Answer:

let the other number be x

2/5*x=-3/7

x=-3/7*5/2

x=-15/4

the other number is -15/4

Step-by-step explanation:

the product of two numbers is -3/7

one number is. 2/5 and the other number is taken as x

and the other steps are being done and when the. 2/5 shift to the right side it is reciprocal of 2/5 which is 5/2

and -3/7 and 5/2 is multiplied and we get -15/4

this will be the other number to be multiplied with 2/5 to get -3/7 as the product

in place of x we can substitute -15/4 we will get the product -3/7
