Ann uses three 1/4 size strips to model3/4

Hey. Let me help you on this one.

Let's take a look at the question. Ann wants to model 3/4 with strips that are only 1/4, or 25% of their original size. 

Since the problem wants us to find 3/4 but show it with strips, we will do addition of the fraction.

3/4 is three out of four, meaning that one additional 1/4 will make the number equal to one. We can use the same logic to determine how much one-fourths are in 3/4.

As we can see, denominator of both fractions are the same, meaning that we don't need to transform them using the ratio. Instead, let's focus on numerators - numbers above denominators.

Three in 3/4 is three times bigger than one in 1/4, and we know that because setting up a quick expression will prove that.



Since 1/4 is three times less than 3/4, we know that three one-fourths are needed for three-fourths.

I will also attach a very helpful image that will aid you in your studies.
