Question

solve and arrange the rational number in ascending order 2/5,-1/2,8/-15, -3/-10

Answer 1

Answer:

Step-by-step explanation:

It will become 2/5 -1/2 -8/15 3/10

LCM = 30

2/5 becomes 12 /30

-1/2 becomes -15/30

-8/15 becomes -16/30

3/10 becomes 9/30

So -16 <-15 <9 <12 so

-8/15 <-1/2 < 3/10 < 2/5

Answer 2

Answer:

Step-by-step explanation

(Taking the LCM of the denominators)

LCM of 2, 5, 15, 10= 30

Therefore, new numbers are

12/30, -15/30, -16/30, 9/30 (note that minus will become plus in the fraction -3/-10 because, -3 and -10 are being divided...hence the sign would be cancelled)

Arrangement:

-16/30, -15/30, 9/30, 12/30

(now reduce them to their simplest forms)

hope it helps you :)
