In most cases yes. Depending on your teacher, as few as two decimal places is enough. Standardized national exams like the SAT / ACT don't allow more than 3 decimal places, and the AP exam requires rounding to exactly 3 decimal places.

How do you know where the decimal point is located in the answer to a multiplication problem with decimals?

Okay so here is an example: 0.25 x 0.30 You move the decimal out from 0.25 towards to the right and you count how many spaces you have to move it. In this case, it's twice. The same goes for 0.30. You count how many times it moves to the right and then you just do 25 x 30 because you've gotten rid of the decimal. Now the answer to 25 x 30 is 750. You then move the decimals back in after you've found the answer. Since you had to move the decimal to two places to te right both times, you add that together to get four so you move the decimal back in, but move it four spaces to the left. Now the answer is 0.0750. Do you get it or is my explainaton a bit confusing? Sorry if it is, I'm not very good at explaining things ----------------------------------------------------- Multiply the numbers as if there were no decimals; then count the decimal places from the right in each number, adding them to the answer. Ex: 4.01 x 2.02 = 8.1002


How do you change a decimal to a fraction?

by either 100 or by 10 for example .67 in a fraction will be 67/100 or .8 as a faction will be 8/10. As above but for each further decimal place you would add a further 0 to the denominator so 0.677 would be 677/1000 and 0.6777 would be 6777/10000 and so on.

Shannom earned 12.30 in Dimes How Many Dimes did Shannon earn?

Okay, all you have to do here is divide 1230 by 10. The answer is 123. She earned 123 dimes. Easier way if you're into decimals. Since the value you're dividing by is ten, just move the decimal over one place to the right. Do you see?
