The least common multiple of six and three is six multiply the numerator and denominator of each fraction by whatever value will result and the denominator of each fraction being equal to the least common factor which is six. When they have like denominators which is the same ones you can add 1/6+2/3 1/6+2/3 times 2 by 2 and 3 by 2 with the 2/3 fraction Then u get 1/6+4/6 =1+4/6 =5/6 Mark brainliest if I helped/answer correct !
