Howard works out the problem below and his answer is below. Is Howard correct if not where did he make his mistake? Explain and give the right answer. What is 40% of 140?

His answer- 4.8

56

Step-by-step explanation:

Howard's answer is completely wrong at least the way I completed the problem. When you want to calculate the percentage of a number in any case you multiply. Instead of multiplying 140 by 40 percent you multiply it by 0.4 (140*0.4) which will give you 56 which is the correct answer and is 40 percent of 140.
