How can you find 40% of 150 using mental math? Explain.<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n To find 40% of 150 using mental math, follow these steps:<\/p>\n\n\n\n The task is to calculate 40% of 150. The term “percent” means “per hundred,” so 40% can be written as a fraction:<\/p>\n\n\n\n [ Thus, the problem becomes finding 0.40 of 150, or simply multiplying 150 by 0.40.<\/p>\n\n\n\n Rather than multiplying 150 directly by 0.40, you can break it down into simpler parts:<\/p>\n\n\n\n [ This can be rewritten as:<\/p>\n\n\n\n [ Now, you need to calculate ( 150 \\times 40 ) first, which is easier to do:<\/p>\n\n\n\n [ Now that we have ( 150 \\times 40 = 6000 ), divide this by 100 to get the final result:<\/p>\n\n\n\n [ You can also verify your answer by using another method. You know that 10% of 150 is 15 (because ( \\frac{10}{100} \\times 150 = 15 )). To find 40%, you can multiply 10% by 4:<\/p>\n\n\n\n [ Thus, 40% of 150 is 60.<\/p>\n\n\n\n The correct answer is 60<\/strong>.<\/p>\n\n\n\n In this process, we simplified the multiplication by breaking it into manageable parts: calculating ( 150 \\times 40 = 6000 ) and dividing by 100. We also verified the result by considering that 10% of 150 is 15, and multiplying this by 4 gives the same result, 60. This mental math method allows for quick and accurate calculations without the need for a calculator.<\/p>\n","protected":false},"excerpt":{"rendered":" How can you find 40% of 150 using mental math?
