Mrs hamid used 7 3/4 cups of flour to bake a cake, a pie and some loaves of bread. she used 3/4 cups of flour to bake a pie and twice as much four to bake a cake.

(a) how many cups of flour did she use to bake the loaves of bread? express your answer as a mixed number in it's simplest form.

(b) she made 2 identical loaves of bread. how many cups of foour did she use to bake a load of bread? give each answer as a mixed number in it's simplest form.

X=cups of flour to bake bread
3/4 cup to bake pie
2(3/4) cups to bake cake

Part One:
x+3/4+2(3/4)= 7 3/4
x+3/4+1 1/2= 7 3/4
x+2 1/4= 7 3/4
Subtract 2 1/4 from both sides
x=5 1/2 cups of flour to bake loaves of bread

Part Two:
To find flour for one loaf:
5 1/2 ÷ 2=
11/2 ÷ 2=
11/2÷2/1=
Invert the fraction and multiply
(11*1) / (2*2)=
11/4= 2 3/4 cups of flour for 1 loaf of bread

Check the
x+3/4+2(3/4)= 7 3/4
5 1/2 + 3/4 + 1 1/2= 7 3/4
7 3/4 = 7 3/4

Hope this helps!! :)
