Which is the best reason why 1 3/10 + 2 5/10 is not equal to 5?
Gelneren [198K]

Answer and Step-by-step explanation:

Let's try to add these two mixed numbers together. We have 1\frac{3}{10} and 2\frac{5}{10}.

First, add the nonfractional parts together:

1 + 2 = 3

Now add the fractional parts. Because 3/10 and 5/10 already have a common denominator (10), we can simply add the numerators together:

\frac{3}{10} +\frac{5}{10} =\frac{3+5}{10} =\frac{8}{10}

Add 8/10 to our whole number 3:

3 + 8/10 = 3\frac{8}{10} =3\frac{4}{5}

Clearly, 3\frac{4}{5} ≠ 5, which is why 1 3/10 + 2 5/10 ≠ 5.

Hope this helps!
