In order to add fractions, the denominators must be the same.

1/2+3/8

Find the least common denominator by prime factorization.

2 : color(red)2

8 : color(red)2, color(blue)2, color(blue)2

To determine the least common denominator (LCD), multiply the common factor color(red)2 times the other factors in blue.

LCD=color(red)2xxcolor(blue)2xxcolor(blue)2=8

Multiply 1/2 times 4/4 so that it will have a denominator of 8.

1/2xx4/4+3/8=

4/8+3/8=7/8
