Theresa's forgot to find a common denominator between the two fractions and instead, tried to add the different denominators together.

Step-by-step explanation:

I believe I found the remaining information required to answer this question.

The worksheet has a drawing of Theresa with a thought bubble. Inside the bubble reads:

¹/₄ + ³/₅ = 1 + 3/4 + 5

Theresa's forgot to find a common denominator between the two fractions and instead, tried to add the different denominators together.

To get the correct answer, you first need to find the least common denominator. In this case, the LCD would be 20. This means I have to convert both fractions to have a denominator of 20.

¹/₄

4 x 5 = 20. This means that I have to multiply both the numerator and the denominator by 5 which gives us ⁵/₂₀

³/₅

5 x 4 = 20. This means that I have to multiply both the numerator and the denominator by 4 which gives us ¹²/₂₀

Now we can add the two up and get ¹⁷/₂₀

the answer is c
