A lasagna recipe calls for 1/4
a cup of sauce
for the bottom layer and 4/5
a cup of sauce for the top layer. How much sauce will you need to make the lasagna?
Step-by-step explanation: First you would multiply 1/4 by 1/5 because of 4/5. Now we have 1/20. Then you would multiply 4 in 4/5 by 4 and 5 by 4. Then you would get 16/20. Then you would add them, 1/20 + 16/20 = 17/20 total sauce
