Carla uses 2 3/4 cups of whole wheat flour and 1 3/8 cups of rye flour in her bed recipe. how many cups does she use in pls explain how u got the answer

4 and 1/8 is your answer.
2 + 1 = 3
3/4 + 3/8 = 1 and 1/8
Add 1 and 1/8 + 3 = 4 and 1/8
I hope this helped! 

2x4+3 = 11/4 (11/4 is equivalent to 2 3/4 cups) 
1x8+3 = 11/8 (11/8 is equivalent to 1 3/8 cups)
11x2 = 22
4x2  =  8
22/8 is equivalent to 11/4

22/8 + 11/8 = 33/8
 She uses 33/8 cups or 4 1/8 cups of flour total

I hope this made sense :))
