Answer:

The answer is #7/8#.

Explanation:

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#
