sarah, how is this problem solved??
3/ x+1  5/x You solve this problem just as you would solve 3/7  5/9. You first need to find a common denominator. With 3/7  5/9 the common denominator is 7 times 9. Thus multiply the numerator and denominator of the first fraction by 9 and multiply the numerator and denominator of the second fraction by 7 to get = 27/63  35/63 = (27  35)/63 = 8/63. Likewise for the algebraic fractions. The common denominator of 3/(x + 1) and 5/x is (x + 1) times x. Thus multiply the numerator and denominator of the first fraction by x and multiply the numerator and denominator of the second fraction by (x + 1) to get Penny
