Question

Colleen compared the ratios 3:8 and 1/2.

Answer 1

Answer:

D.The fraction $\frac{1}{2}$ should have been rewritten as $\frac{4}{8}$.

Step-by-step explanation:

We are given that ratios as fraction

$\frac{3}{8}$ and $\frac{1}{2}$

Colleen compared between given ratios

We have to find the first mistake of Colleen in her work.

First we make denominator of both fraction same

Therefore, we will divide and multiply by 4 in second fraction number

$\frac{1}{2}\times \frac{4}{4}=\frac{4}{8}$

The numerator of $\frac{4}{8}$ is greater then the numerator $\frac{3}{8}$.

Hence, the $\frac{4}{8} >\frac{3}{8}$

Therefore, option D is true.

Answer:D.The fraction $\frac{1}{2}$ should have been rewritten as $\frac{4}{8}$.

Answer 2

To compare two fraction you need to rewrite the fractions so they have a common denominator.
