Answer:

4 7/8

Explanation:

Okay so you need help adding these fractions.

You can start by converting both into improper fractions

For the first one

1 3/4 ====> you multiply 1 by 4 and add the sum to the numerator the improper fraction becomes ===> 7/4

Do the same for the other

3 1/8 ====> 25/8

To add these you have to get a common denominator.

The LCD is 8

So to get the other fraction to have the same denominator you must multiply both top and bottom by 2.

7/4 * 2/2 = 14/8 so now you have to add.

14/8 + 25/8

= 39/8

Now simplify (to simplify you have to divide 39 by 8)

See how many times 8 can go into 39

4 times which equals 32 the remainder is 7 so your final answer would be:

4 7/8

Hope this helps

Explanation:

Rewriting our equation with parts separated

1+3/4+3+1/8

Solving the whole number parts

1+3=4

Solving the fraction parts

3/4 + 1/8

Find the LCD of 3/4 and 1/8 and rewrite to solve with the equivalent fractions.

LCD = 8

6/8+1/8=7/8

Combining the whole and fraction parts

4+7/8= 4 7/8
