express each sum or difference as a single fraction in simplest form

*Since 6/3=2, you can combine the "a" terms. *10ab + (a^{2}b)/5 - a + (6/3)a =

*Look for common denominator. It's 5.* (50/5)ab + (1/5)(a^{2}b) + (5/5)a =

*Combine all terms in the numerator and divide by common denominator.* (50ab + a^{2}b + 5a)/5

Hi, Kathy. Can you rewrite the problem so it's a little more clear? It's hard to tell how it is supposed to written; for example, is 10ab the first term or is 10ab+1 the numerator of a fraction? When writing problems in linear style, you can use parentheses around numerator and denominator values to separate them.
