Answer 2

Step-by-step explanation:

I am going to show you an example with the first question, and you will apply it on the rest on your own ^^

Step 1:

convert the mixed number fractions into improper fractions:

To do that you need to multiply the whole Number by the denomiator and add it to the numerator.

$2\frac{1}{2}$+$1\frac{7}{8}$= $\frac{5}{2}$+$\frac{15}{8}$

Step 2:

Now you want the denominators of both fraction to be equal so that you can add them:

$\frac{5x4=20}{2x4=8}$ + $\frac{15}{8}$

Step 3:

Add.

=$\frac{20}{8}$+$\frac{15}{8}$

=$\frac{35}{8}$

Step 4:

Turn the improper fraction back to a mixed number fraction:

$\frac{35}{8}=4\frac{3}{8}$

There it is!

Bonus information:

For adding or subtracting fractions, you need a common denominato.

For multiplying fractions you do not need a common denominator, just mutiply the numerators together and the denominators together.

For dividing fraction, you do Not need a common denominator either. Just switch the two parts of the second fraction (so the numerator goes in the place of the denominator and vice versa) and multiply the two fractions!

I really hope this helped ;)
