Find common denominators and calculate each of the following sums. 3/8+1/4

5/8

Step-by-step explanation: there are two way to do it

3/8 + ( 4x2=8, 1x2=2) 2/8 = 3+2=5 which is 5/8  16= (8x2=16,3x2=6) 16=( 4x4=16, 1x4=4) 6/16 + 4/16= 10/16, (10÷2=5 16÷2=8) = 5/8 then reduce to lowest                                                                                                                                        8 is the LCD of the sum 3/8+1/4
