Question

A man weighs 51 kilograms. His brother weighs 10 percent more. How heavy is the brother? 5.1 kilograms 51.6 kilograms 55.6 kilograms 56.1 kilograms

Answer 1

Answer: 56.1 kilograms

Explanation:

Solution 1: Multiply 51 by 10% and we'll get 5.1. Then, add 51 and 5.1 and we'll get 56.1

Solution 2: Multiply 51 by 110% and we'll get 56.1

(we can multiply 51 by 1 + 10% because multiplying 51 by 1 is the same thing as multiplying 51 by 100%. So you can just use this slicker formula for solving problems like this)
