Question

compare -7/8 and 17/-18
​

Answer 1

Answer: Taking 10/11 and 17/18.

We will first make them like.

So,we will get,

180/198 and 187/198

Since, 187 is grater then 180. So,

187/198 is grater then 180/198

Now, taking -5/12 and -3/4

We will make them like.

So,we will get,

-5/12 and -9/12

Since,-5 is grater then -9.So,

-5/12 is grater then -9/12

Answer 2

⇒17/-18 = -17/18

LCM of 8 and 18:

8= 2×2×2

18= 2×3×3

LCM= 2×2×2×3×3=72

⇒-7/8 × 9/9 = -63/72

⇒-17/18 × 4/4 = -68/72

∵ -68/72 ∠ -63/72

∴ -17/18 ∠ -7/8
