Answer:
Total flour used = 3 1/6 c
Step-by-step explanation:
Whole wheat flour = 1 1/2 c
Buckwheat flour = 1 2/3 c
How much flour did he use in all?
Total flour used = Whole wheat flour + buckwheat flour
= 1 1/2 c + 1 2/3 c
= 3/2 c + 5/3 c
= (9c + 10c) / 6
= 19c/6
= 3 1/6 c
Total flour used = 3 1/6 c
