Lila decided to make more baked goods for the bake sale. She used 1/8 less flour to make bread to make cookies. She used 1/4 more flour to make cookies than to make brownies. If she used 1/2 of flour to make the bread, how much flour did she use to make the brownies. Explain your answer.
Answer:
3/7 cup
Step-by-step explanation:
Ignore the units for the time being. Just to give it units, you could call it cups. This question is really about ratios.
Let the cookies = x
Then the bread = x - 1/8 x = 7/8x
The brownies = cookies - 1/4 cookies
The brownies = 3/4 cookies = 3/4 x
==============
Now start again.
The bread uses 1/2 cup.
That translates into 1/2 = 7/8 x
x = 1/2 // 7/8 = 4/7 cup for the cookies (4/7 is larger than 1/2)
Whatever the cookies are, the brownies take 3/4 as much
4/7 * 3/4 = 12/28 = 3/7
The answer should be 3/7 of a cup.
9514 1404 393
Answer:
3/8 lb
Step-by-step explanation:
If all units are pounds, then we have ...
bread = cookies - 1/8 lb
cookies = brownies + 1/4 lb
bread = 1/2 lb
Using the last value in the first equation, we find ...
1/2 lb = cookies - 1/8 lb
cookies = 5/8 lb . . . . . . . add 1/8 lb to both sides
Using this in the second equation gives ...
5/8 lb = brownies + 1/4 lb
3/8 lb = brownies . . . . . subtract 1/4 lb from both sides
__
Lila used 3/8 lb of flour to make the brownies.

Nine pieces of 8 in. ✕ 12 in. duct that is 2 2 3 ft in length is needed for a building. What is the total length (in ft) needed?
This question is incomplete, the complete question is;
Nine pieces of 8-in. × 12-in. duct that is 2[tex]\frac{2}{3}[/tex] ft in length is needed for a building. What is the total length (in ft) needed?
Answer:
the total length needed is 24 ft
Step-by-step explanation:
Given the data in the question;
the length of one piece of 8-in. × 12-in. duct is 2[tex]\frac{2}{3}[/tex] ft
Now to find the total length for nine pieces of the duct;
we simple multiply 2[tex]\frac{2}{3}[/tex] ft by nine
so
Total length = 9 × 2[tex]\frac{2}{3}[/tex]
we convert the mixed fraction to improper fraction
2[tex]\frac{2}{3}[/tex] = 8/3
so
Total length = 9 × (8/3) ft
Total length = 24 ft
Therefore, the total length needed is 24 ft

Find x
To solve for x, we make use of the following equivalent ratio
[tex]4 : 6 = x : 12[/tex]
Convert to fractions
[tex]\frac{4}{6} = \frac{x}{12}[/tex]
Multiply both sides by 12
[tex]12 * \frac{4}{6} = \frac{x}{12} * 12[/tex]
[tex]12 * \frac{4}{6} = x[/tex]
[tex]x = 12 * \frac{4}{6}[/tex]
[tex]x = \frac{12 * 4}{6}[/tex]
[tex]x = \frac{48}{6}[/tex]
[tex]x = 8[/tex]
