Question

The product of two rational no is 15/56.If the one no is -5/48. Find the another no

Answer 1

hi!

Answer: -18/7

Step-by-step explanation:

Let the other no. be x

x × -5/48 = 15/56

x = 15/56 × -48/5

x = 3/7 × -6 (after cross multiplication)

x = -18/7 (answer)

hope it helped! :)

Answer 2

Answer:

-18/7 is the other number.

Step-by-step explanation:

let the other number be x

=> The product of two rational no is 15/56

=> One of the number is -5/48

$=>(\frac{-5}{48} )(x)=\frac{15}{56} \\\\=> x=(\frac{15}{56})/(\frac{-5}{48})\\\\=> x=(\frac{15}{56})(\frac{48}{-5} )\\\\=>x=\frac{(-3)(6)}{7} \\\\=>x=\frac{-18}{7}$

=> the other number is -18/7
