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
1/3x=1/6
x/3=1/6
cross multiply
6x=3
divide both sides by 6
x=3/6
x=1/2
so 3 x 109 =327+ 1 =328
i think. so freds age is 3 times her age plus one so 328
