Question

4.The product of two numbers is 2 ½. If one of them is 5, find the other number?

Answer 1

Answer:

other number is 1/2

Step-by-step explanation:

2x1/2 divide by 5

1/2

Answer 2

The product of two numbers is 2 ½ and if one number is 5 then we need the following assumption to proceed:

let the two numbers be a and b respectively.

⇒ a×b = 2 ½

converting it into rational form for easy calculation.

⇒ a×b = 5/2

also, one of the given numbers say a = 5

⇒ 5×b = 5/2

By dividing the LHS and RHS of the equation by 5, we get the value of the other number b=1/2.
