Students are painting a mural. so far the mural is painted 1/4 blue 2/8 red and 3/12 green. use fraction strips to determine how much of the mural has been painted. tell the fractions you use to solve

If you make the denominators all the same, the fractions are 3/12 , 3/12 , and 3/12. Then by simply adding them together you get that the mural is 9/12 painted. that then simplifies to  3/4 or 75%

Hope this helps :)
