Answer 1

Answer:

$\boxed{\boxed{\sf\frac{11}{8}=1\frac{3}{8} =1.375}}$

Solution Steps:

______________________________

1.) Find the LCF of 8 and 4:

• $8,4=8$

 - We do this because in order to add the fractions together, they have to have the same denominator. In this case you find the LCF, (Least Common Factor) of 8 and that turns into the denominator for both.

2.) Convert the fractions to have the same denominator:

• $\frac{5}{8}=\frac{5}{8}$

• $\frac{3}{4}=\frac{6}{8}$

 - $\frac{5}{8}$ stays the same, but $\frac{3}{4}$ changes to $\frac{6}{8}$ because the LCF if 8, and to get to 8 we had to multiply 4 by 2. So since we multiplied the denominator, you must do the same to the numerator, hence why we went from 3 to 6.

3.) Add the numerators:

• $5+6=11$

 - Since $\frac{5}{8}$ and $\frac{6}{8}$ have the same denominator, all you have to do is add the numerator.
