chocolate cakes, and 2
caramel cakes. On the second day, she sold
of a chocolate cake and 3
caramel cakes.
Which statement tells the total number of cakes she sold and explains how the total can be calculated?

A First, find the least common multiple and change only the denominators: 2
+ 2
+
+ 3
= 7
. Next, simplify: 7
= 8.First, find the least common multiple and change only the denominators: 2 1 8 + 2 3 8 + 3 8 + 3 1 8 = 7 8 8 . Next, simplify: 7 8 8 = 8.
B Change the fractions to make denominators common, and then add: 2
+ 2
+
+ 3
= 7
. Next, simplify: 7
= 8
.Change the fractions to make denominators common, and then add: 2 2 8 + 2 3 8 + 6 8 + 3 4 8 = 7 15 8 . Next, simplify: 7 15 8 = 8 7 8 .
C Change the numerators to 3 to make them common, and then add: 2
+ 2
+
+ 3
= 7
. Next, simplify: 7
= 7
.Change the numerators to 3 to make them common, and then add: 2 3 12 + 2 3 8 + 3 4 + 3 3 6 = 7 3 30 . Next, simplify: 7 3 30 = 7 1 10 .
D Add across the numerators and denominators first:
+
+
+
=
. Next, add whole numbers 2 + 2 + 3 = 7, then combine: 7
chocolate cakes, and 2
caramel cakes. On the second day, she sold
of a chocolate cake and 3
caramel cakes.
