Question

The difference between the greatest and the least numbers of 5/3, 7/2, 4/10, 2/9 is
a. -18/15. b.-8/45. c.-11/5. d.59/18

Answer 1

5/3 , 7/2 , 4/10 , 2/9

firstly we have to make the denominator same

so, we take the lcm of denominators

lcm = 90

now we will multiply each no. with lcm one by one

1. 5

-- × 90 =150

3

2. 7

-- × 90 = 315

2

3. 4

-- × 90 = 36

10

4. 2

-- × 90 = 29

9

from this we observe that 7/2 is the greatest while 2/9 is the smallest no.

now we will find difference between 7/2 and 2/9

7 2 7×9 - 2×2 63 - 4 59

-- - -- = -------------- = ---------- = ------

2 9 2×9 18 18

therefore option d 59/18 is correct

please mark me as brainliest
