Question

The numerator of a fraction is 18 and the denominator is 8. All of the following numbers are equivalent except: a.9/4 b.2 1/4 c. 36/16 d. 6/4

Answer 1

Answer:

The correct answer option is d. 6/4.

Step-by-step explanation:

If the numerator of a fraction is 18 and the denominator is 8, we can write it as $\frac{18}{8}$ which is a improper fraction.

$\frac{18}{8}$ can be written as $2\frac{1}{4}$ in its mixed form.

So we will check which of the options equal $2\frac{1}{4}$.

a) $\frac{9}{4} = 2\frac{1}{4}$

b) $2\frac{1}{4} = 2\frac{1}{4}$

c) $\frac{36}{16} = 2\frac{1}{4}$

d) $\frac{6}{4}$ $= 1\frac{1}{2}$

Therefore, d. 6/4 is not equivalent to 18/8.

Answer 2

All of the following numbers are equivalent except: b. 2 1/4
