A fruit company ships boxes of apples and pears in a crate that measures
vfiekz [6]

Answer:

  none of the above

Step-by-step explanation:

The crate has a volume of ...

  V = LWH = (15 in)(18 in)(24 in) = 6480 in³

The apple box has a volume of ...

  V = LWH = (15 in)(15 in)(10 in) = 2250 in³

The pear box has a volume of ...

  V = LWH = (12 in)(12 in)(12 in) = 1728 in³

__

Together, one box of each fruit takes up a volume of ...

  (apple box) + (pear box) = (2250 in³) + (1728 in³) = 3978 in³

Then the part of the crate not filled has a volume of ...

  6480 in³ -3978 in³ = 2502 in³ . . . . not among the answer choices

How much is 1 1/4 + 3/4 + 1 1/3 step by step
dangina [55]

Answer:

  3 1/3

Step-by-step explanation:

<u>Step 1</u> is to look at the problem.

Here, you notice that the first two numbers have fractions that are quarters. The total of those two fractions is 1/4 + 3/4 = 4/4 = 1.

So, the sum of the first two numbers is ...

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

<u>Step 2</u> is to add the next mixed number, which has a fraction with a different denominator. Since you have no fractions to add at this point, the sum is just ...

  2 + 1 1/3 = 3 1/3

_____

<em>Comment on adding fractions</em>

Generally, adding fractions requires you determine a common denominator. Often, you are asked to find the <em>least</em> common denominator, but that isn't necessary. Sometimes that can save the work of reducing the fraction that results, but sometimes it makes more work.

Here, a common denominator for fourths and thirds would be twelfths:

  1/4 = 3/12

  1/3 = 4/12

However, since adding the fourths results in an integer, no common denominator is necessary.
