Which number is larger? Explain. (a) 8 7 and 9 7 8 7 is larger because both are bigger than one. 9 7 is larger because of the larger numerator. 8 7 is larger because it has the smaller cross-product. 9 7 is larger because the size of the equal-sized parts is larger. (b) 12 5 and 12 8 12 5 is larger because both are bigger than one. 12 8 is larger because of the larger denominator. 12 8 is larger because it has the smaller cross-product. 12 5 is larger because the size of the equal-sized parts is larger. (c) 5 6 and 8 7 8 7 is larger because it is bigger than one and 5 6 is not bigger than one. 5 6 is larger because of the smaller numerator. 5 6 is larger because it has the smaller cross-product. 8 7 is larger because the size of the equal-sized parts is larger
