Answer:

35 and 36

Explanation:

To solve this problem, we must interpret it line by line;

  • We are dealing with consecutive integers; these are integers with a difference of 1 between them.

let the first number = x

second number = x + 1

  • one - fifth of first;


(1)/(5)x

  • one - ninth of the second;


(1)/(9)(x + 1)

for the "less" ;


(1)/(5)x -
(1)/(9)(x + 1) = 3

Multiply through by 45

45(
(1)/(5)x) - (45)
(1)/(9)(x + 1) = 3 x 45

9x - 5(x + 1) = 135

9x - 5x -5 = 135

4x = 135 + 5

4x = 140

x = 35

Now, x+1 = 35 + 1 = 36

The consecutive integers are 35 and 36
