Beulah used 3/5 pounds of dough, 3/4 pound of sugar, & 2/3 pounds of sprinkles to make donuts. how many pounds of donuts did beulah make? type answer as a mixed-number fraction.

If we want to know the total amount of pounds of donuts, we firstly have to make a sum of each element Beulah used to make her donuts:

where D is the total pounds of donuts made.

In order to solve this, we have to take the Lowest Common Denominator, this means that we have to multiply de denominators to obtain a common denominator, in this case the value is:

this is the common denominator now. Then we have to divide this value by each denominator and then multiply the result with each numerator, as follows:

with the following result:

This is D, the total pounds of donuts made.

Now, we need to express this as a mixed-number, in this case we have to:

having the final result:

the answer is c.
