Answer 1

The only correct options are A, B and E.

Explanation:

He buys
`1(1)/(2)` pounds of flour, 12 ounces of coconut, and
`1(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 =
`(3)/(4)` pounds

He buys
`(3)/(4)` pounds of coconut.

Adding all of them together yields:

`1(1)/(2)` +
`(3)/(4)` +
`1(1)/(4)` =
`3(1)/(2)` pounds

Let us also convert to ounces:

`3(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(1)/(2)` pounds or 56 ounces or 3 pounds 8 ounces

Hence, options A, B and E are correct.
