Answer 2

Step-by-step explanation:

is 30,

so 1/10 = 3/30

2/15 = 4/30

But we cant find no.s between 3 and 4, so we will multiply both fractions by 6.

= 18/180 and 24/180

Four numbers between them are 19/180, 20/180, 21/80, 22/180, 23/180

Therefore, the answer is, 19/180, 1/9, 21/80, 11/90, 23/180

Hope this helps.
