Dwayne buys ingredients to make a cake. He buys 112 pounds of flour, 12 ounces of coconut, and 114 pounds of sugar. What is the
Anastaziya [24]

Answer:

The only correct options are A, B and E.

Step-by-step explanation:

He buys 1\frac{1}{2} pounds of flour, 12 ounces of coconut, and 1\frac{1}{4} pounds of sugar.

We will add these together, but before that, we convert the 12 ounces to pounds, so that all the units are the same:

1 ounce = 0.0625 pounds

12 ounces = 12 * 0.0625 = \frac{3}{4} pounds

He buys  \frac{3}{4} pounds of coconut.

Adding all of them together yields:

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

Let us also convert to ounces:

3\frac{1}{2}  / 0.0625 = 56 ounces

Let us also convert 1/2 pound to ounces:

1/2 / 0.0625 = 8 ounces

Hence, the total weight of ingredients that Dwayne bought is 3\frac{1}{2} pounds or 56 ounces or 3 pounds 8 ounces

Hence, options A, B and E are correct.
