1 first find least common factor sense the denominators ar different witch will be ten then then the number you used to multiply the denominator to find 10 you use to multiply the numerator with.
so you left with 6/10 + 7/10 witch equals 13/10
2 do the same in 1 find least common factor witch is 12 and then multiply the number used to get the common factor by the numerator witch leaves the setup as 8/12+3/12 witch equals 11/12
