Meera needs 2 3/4 cups of flour for a batch of cookies and 3 1/3 flour for a dozen muffins. How many cups of flour does Meera need altogether

2 3/4+ 3 1/3

2 3/4 = 11/4

3 1/3= 10/3

11/4+10/3

33/12 + 40/12

73/12

=6 1/12

Step-by-step explanation:

firstly you change the fractions into improper fractions then you find the L.C.M of 3 and 4 which is 12 and you have to do 3×4 to get 12 then 10 × 4 which is 40 because what you do at the bottom you also have to do at the top then you do 4×3 to get 12 then you do 11×3 to get 33 because what you do at the bottom you also have to do at the top. then you do 73/12 which gives you 6 1/12

hope this was helpful
