Question

Here is a list of four fractions. 3/15 2/10 5/20 15/75 One of these fractions is not equivalent to 1/5

Answer 1

Answer:

5/20 is not equivalent to 1/5.

Step-by-step explanation:

We can start by simplifying all of the fractions, by finding numbers we can divide both the numerator and denominator by the same number.

$\frac{3}{15} =\frac{1}{5}$ by dividing by 3.

$\frac{2}{10} =\frac{1}{5}$ by dividing by 2.

$\frac{5}{20} =\frac{1}{4}$ by dividing by 5.

and last but not least

$\frac{15}{75} =\frac{1}{5}$ by dividing by 15.

We can see that 5/20 is the only one that equals to 1/4 when simplified.

Therefore, 5/20 is not equivalent to 1/5.

Hope this helped! Have a great day!

Answer 2

5/20 isn’t equivalent to 1/5.

To find out what fractions are equivalent, we can cross multiply:

Let’s set up 3/15 and 1/5 first.

3 • 5 = 15
15 • 1 = 15

Therefore, they are equivalent.

Let’s now set up 2/10 with 1/5:

2 • 5 = 10
10 • 1 = 10

Therefore, they are equivalent.

Let’s now set up 15/75:

1 • 75 = 75
15 • 5 = 75

Therefore, they are equivalent.

Finally, let’s set up 5/20:

1 • 20 = 20
5 • 5 = 25

Therefore, 1/5 is not equivalent to 5/20.

Answer Recap: 5/20 is not equivalent to 1/5.
