Answer 1

Answer:

Step-by-step explanation:

NUMBERS : 2/9 AND 4/7.

SUM = 2/9+4/7

        = (2*7+4*9)/9*7

        = (14+36)/63

        = 50/63

DIFFERENCE = 4/7-2/9

                      = (4*9-2*7)/9*7

                      = (36-14)/63

                      = 22/63

RATIO = SUM / DIFFERENCE

           = (50/63)/(22/63)

           = 50/22

           = 25/11.

HOPE THIS HELPS.

Answer 2

Answer:

given: to add 2/9 and 4/7 and divide the sum by their difference

sum = 2/9 + 4/7

=> (14 + 36)/63

=> 50/63

difference = 2/9 - 4/7

=> (14 - 36)/63

=> -22/63

now 50/63 ÷ -22/63

=> 50/63 × 63/-22

=> 50/-22

=> -25/11
