Answer:
a) The unit rate are:
Batch A = 3 3/4 flour per cup of chocolate chips
Batch B = 4 flour per cup of chocolate chips.
b)Batch A is the cookie with the most chocolate chips.
Step-by-step explanation:
In batch A you use 3/4 of a cup of flour to every 1/5 of a cup of chocolate chips.
The unit rate for flour per cup of chocolate chips for batch A =3/4 cups of flour ÷ 1/5 cup of chocolate chips
= 3/4 ÷ 1/5
= 3/4 × 5/1
= 15/4
= 3 3/4 flour per cup of chocolate chips.
In batch B you use 2/3 of a cup of flour for every 1/6 of a cup of chocolate chips.
The unit rate for flour per cup of chocolate chips for batch B =
2/3 of a cup of flour ÷ 1/6 of a cup of chocolate chips.
= 2/3 ÷ 1/6
= 2/3 × 6/1
= 4 flour per cup of chocolate chips.
b)
Number of chocolate chips used in Batch A = 1/5 cup =>0.2 cup
Number of chocolate chips used in Batch B = 1/6 cup => 0.167 cup
0.2 cup is larger than 0. 167 cups.
Therefore, Batch A is the cookies with the most chocolate chip
