Math when is the sum of two negative mixed numbers an integer

Mathematics

FrozenT [24]3 years ago

The short answer is: when their fractions add up to full integers.

For examples, two halves make up a whole, or

\frac{1}{2} + \frac{1}{2}=1

so the mixed numbers with those will add up to full integers:

-12\frac{1}{2} + (-3\frac{1}{2})=(-(12+3+1)=-16

but if they don't add up to an interger, the whole sum won't be an integer:


-12\frac{3}{4} + (-3\frac{3}{4})=(-(12+3+1\frac{1}{2})=-16\frac{1}{2}

Joe has a bag of blocks. 3 red blocks and 2 blue blocks weigh 24 ounces while 1 red block and 3 blue blocks weigh 16 ounces. Def
fredd [130]

Answer: 3r + 2b = 24

r + 3b = 16

Step-by-step explanation:

Let the red blocks be represented by r

Let blue blocks be represented by b

Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:

3r + 2b = 24

1 red block and 3 blue blocks weigh 16 ounces. This will be:

r + 3b = 16

Therefore, the equation will be:

3r + 2b = 24

r + 3b = 16
