7nadin3 [17]

Answer:

$\frac{5}{12} \ of\ a \ pint$ .

Step-by-step explanation:

Given:

Kerry and her brother and noticed there is 3/4 of a pint of ice cream in the freezer.

After they eat some ice cream there is 1/3 of a pint left.

Question asked:

How much ice cream did Kerry and her brother eat ?

Solution:

Total ice cream in the freezer = $\frac{3}{4} \ of\ a\ pint$

Ice cream left = $\frac{1}{3}\ of\ a \ pint$

<h3>They ate = Total ice cream in the freezer - Ice cream left after they ate</h3>

$=\frac{3}{4} -\frac{1}{3} \\ \\\\Taking \ LCM \ of 4 \ and\ 3, we \ got ,12\\ \\=\frac{3\times3-4\times1}{12} \\\\ =\frac{9-4}{12} \\ \\ =\frac{5}{12}$

Thus, Kerry and her brother ate $\frac{5}{12} \ of\ a \ pint$ .

A.6/5 divided by -3/2

Dmitriy789 [7]

A is -12/15 (4/5)
B is 35/12
C is 56
D is 8/15
Sorry if any of these are wrong.
To check them, turn any mixed number into an improper fraction. Then, multiply by the reciprocal. Ex: 4/0 divided by 1/3
X reciprocal- 4/0 times 3/1
