Answer 1

Answer:

Let the common multiple be x

Let the common multiple be xThen,

Let the common multiple be xThen,According to given question,

Let the common multiple be xThen,According to given question,11x−7x=20

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20⇒x=5

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20⇒x=5Therefore

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20⇒x=5ThereforeThe first number =7x=7×5=35

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20⇒x=5ThereforeThe first number =7x=7×5=35Second number is =11x=11×5=55

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20⇒x=5ThereforeThe first number =7x=7×5=35Second number is =11x=11×5=55Then the total is 11x+7x=18x=18×5=90

Let the common multiple be xThen,According to given question,11x−7x=20⇒4x=20⇒x=5ThereforeThe first number =7x=7×5=35Second number is =11x=11×5=55Then the total is 11x+7x=18x=18×5=90Hence, this is the answer.
