question:Choose the expression that has the same value. 5/19+6/198/19 A) 11/19 C) 11/19 +8/19 B) 14/19 D) 5/6 + 6/8

answer:We need to simplify 6/19 + 6/198. The least common multiple of 19 and 198 is 2078. We can write: 6/19 + 6/198 = (6*110 + 6)/2078 = 726/2078 Now, we can rewrite the expression as: 5/19 + 726/2078 = (5*109 + 726)/2078 = 1255/2078 Therefore, the answer is A) 11/19, since it is equivalent to 1255/2078.

question:Which property is shown? 6+(8+11) (6+8) + 11 A) Associative Property B) Commutative Property C) Identity Property D) Distributive Property

answer:D) Distributive Property

question:Choose the equivalent expression. 46/79 +32/42 A) 79 C) 32 +42 B) 32/42 +46/79 D) 32/42

answer:We want to simplify the sum of 46/79 and 32/42. To do this, we need to find a common denominator. One way to do this is to find the least common multiple (LCM) of 79 and 42, which is 1314. We can convert each fraction to have a denominator of 1314: 46/79 = (46 x 18)/(79 x 18) = 828/1314 32/42 = (32 x 31)/(42 x 31) = 992/1314 Now we can add the fractions: 828/1314 + 992/1314 = (828 + 992)/1314 = 1820/1314 This fraction can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 182: 1820/1314 = (182 x 10)/(182 x 7) = 10/7 Therefore, the equivalent expression is B) 32/42 + 46/79.
