Question

Arrange the rational number in ascending order -3/4,2/5,16/15,-1/3

Answer 1

Answer:

-3/4, -1/3, 2/5, 16/15

Step-by-step explanation:

Let's find the LCM of all the denominator s ...

we get , LCM= 60 (because 60 is divisible by 4, 5, 15 and 3)

Now, by equaling the rational numbers...

Step... (we need 60 denominator)

(-3/4) × (15/15) = -45/60 【4 × 15 =60】.....(1)

(2/5) × (12/12) = 24/60 【5 × 12 =60】....(2)

(16/15) × (4/4) = 64/60 【15×4 =60】....(3)

(-1/3) × (20/20) = -20/60 【3×20 =60】...(4)

From (1), (2), (3), (4)

Ascending= (1), (4), (2), (3)

Hence,

Order = -45/60, -20/60, 24/60, 64/60

So, -3/4, -1/3, 2/5, 16/15

Answer 2

Step-by-step explanation:

Lcm of the denominator of all the rational number

LCM of 4, 5, 15, 3 = 60

-3x15/4x15 = -45/60

2x12/5x12 = 24/60

16x4/15x4 = 64/60

-1x20/3x20= -20/60

Ascending order = -45/60 < -20/60 < 24/60 < 64/60

I hope it helps.
