Question

1. The product of two rational numbers is 28/27 of which one of the numbers is - 4/9
Find the other number.
2. If x = 23 and y = 32, then find the value of ( x + y ) divided by ( x - y )

Answer 1

Step-by-step explanation:

hey...

1..28/27=-4/9*x

x=other rational no.=-7/3

2..(x+y)/(x-y)===23+32/23-32===

55/(-9)===-55/9

Answer 2

Answer:

1. 7/3

2. 55/(-9)

Step-by-step explanation:

1. Product = 28/27

  One no. = 4/9

  Other no. = (28/27)÷(4/9)

                   = $\frac{28}{27}$ ÷ $\frac{4}{9}$

                   = $\frac{7}{3}$

2. x=23

   y=32

   $\frac{x+y}{x-y}$

   = (23+32)/(23-32)

   = 55/(-9)

   = -55/9

   = $\frac{-55}{9}$
