What is rounding a number to a one nonzero digit?
It is front-end estimation.
What kind of divisor is most likely to lead to a wrong estimation?
There is no such thing. Although a sloppy choice of an estimate for the divisor will result in a result which is far from the true value, a carefully chosen estimate for the divisor will prevent that.
Does take and get mean the same thing?
No, take and get are not the same thing. One could 'take' a vacation but they would not 'get' one
What is the differentiate mean?
It means to explain the differences between one thing and another thing. For example: Can you differentiate "power" and "force"? Or, can you differentiate "history" and "myth"?
What is the decimal for 7 twentieths?
Answer: .35 Solution Method: d = 7 / 20 d = .35 ==== Previous answer: My apologies-I was thinking of twenty-seconds and all the seconds, but I didn't say TO use a calculator only that he CAN use a calculator. Another alternative to solving the problem, which may or may not be easier, is to realize 20 is a fifth of one hundred, and by multiplying it by five you will get 100. Do the same thing to 7, because whatever you do to the bottom, you do to the top. 7x5=35. Now you have 35 out of 100, which is 0.35, and you can achieve that by dividing 35 by 100. Writing mathematical problems out is more beneficial than using a calculator, as you learn more and remember the solution to the problem more easily.
