MULTIPLE CHOICE QUESTION

3 mins • Ungraded

does the following pair represents the same rational number? (-7/21) and (3/9)

yes

no

Answer explanation

-7/21 = 3/9

-1/3 = 1/3

∵ -1/3 ≠ 1/3

∴ -7/21 ≠ 3/9

So, the given pair does not represent the same rational number.

MULTIPLE CHOICE QUESTION

3 mins • Ungraded

Which is greater in the following: -5/6, -4/3

-5/6

-4/3

Answer explanation

The LCM of the denominators 6 and 3 is 6

∴ (-5/6) = [(-5 × 1)/ (6 × 1)] = (-5/6)

And (-4/3) = [(-4 × 2)/ (3 × 2)] = (-12/6)

Now,

-5 > -12

So, (-5/6) > (- 12/6)

∴ -5/6 > -12/6

Hence, – 5/6 is greater.
