Which is the best reason why 1 3/10 + 2 5/10 is not equal to 5?

Answer and Step-by-step explanation:

Let's try to add these two mixed numbers together. We have and .

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:

Add 8/10 to our whole number 3:

3 + 8/10 =

Clearly, ≠ 5, which is why 1 3/10 + 2 5/10 ≠ 5.

Hope this helps!

First, add the whole numbers

1 + 2 = 3

Second, add both fractions.

3/10 + 5/10 = 8/10

Third, simplify the fraction.

4/5

Fourth, put the number back together.

3 4/5

As you can see, 3 4/5 ≠ 5.

Best of Luck!

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
