Lila collected the honey from 3 of her beehives. From the first hive she collected 2/3 gallon of honey. The last two hives yield
slamgirl [31]

Answer:

a). Lila collected 7/6 gallon in all.

b). She used for baking 5/12 gallon.

c) was left 1/3 gallon of honey

D) She used 3/8lb flour to make the brownies.

Step-by-step explanation:

a). Lila collected 7/6 gallon in all.

\frac{2}{3} +\frac{1}{4} +\frac{1}{4} \\

LCM=3*4=12

\frac{8+3+3}{12}=14/12=7/6

b). She used for baking 5/12 gallon.

She had 7/6 gallon of honey. She used 3/4 gallon for baking. To know how much honey was left, you have to substract 3/4 gallon from the total available honey 7/6 gallon.

\frac{7}{6}-\frac{3}{4}

You need to find LCM to substract fractions with different denominator:

LCM=12

\frac{14-9}{12}=\frac{5}{12}

c) was left 1/3 gallon of honey

To know how much honey was left you need to substract from the initial quantity of honey that is 3/4 gallon, the quantities used for baking, that are 1/6 gallon and 1/4 gallon.

Less common multiple: 12

\frac{3}{4}-\frac{1}{6} -\frac{1}{4}

We use LCM 12 to substract:

\frac{9-2-3}{12}=\frac{4}{12} =\frac{1}{3}

D) She used 3/8lb flour to make the brownies.

You know she used 1/2 lb flour to make the bread and to make cookies 1/8 more. So you need to do following math:

d)\frac{1}{2} +\frac{1}{8} =\frac{4+1}{8} =\frac{5}{8}

She used 5/8 to make cookies and she used 1/4 more to make cookies than brownies, then you have to do following math;

\frac{5}{8}-\frac{1}{4}=\frac{5-2}{8}=\frac{3}{8}
