Question

Please Help me with this Math Assignment

Answer 1

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(1)/(2)`+
`1(7)/(8)`=
`(5)/(2)`+
`(15)/(8)`

Step 2:

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

`(5x4=20)/(2x4=8)` +
`(15)/(8)`

Step 3:

Add.

=
`(20)/(8)`+
`(15)/(8)`

=
`(35)/(8)`

Step 4:

Turn the improper fraction back to a mixed number fraction:

`(35)/(8)=4(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 ;)
