How do you determine number of decimals in the product of two numbers?
Consider the numbers A and B where A has m digits after the decimal point and B has n digits.Then find the multiple A'*B' where A' is A without its decimal point, and B' is B without its decimal point.In that answer insert the decimal point so that there are (m+n) digits after the decimal point.
What does find a terminating decimal mean?
It is a requirement to find a decimal representation which has only a finite number of digits after the decimal point.
How do you devide with a decimal?
There are several ways. My preference with terminating decimals, is to carry out the division using the divisor without a decimal point. Then if the divisor had n digits after the decimal point, it is to move the decimal point in the quotient n places to the left.So, to calculate 18/4.32,first find 18/432 = 0.0416... with the 6 repeating4.32 has two digits after the decimal point so move the decimal point two digits to the left to give the final answer as 4.16 with the 6 repeating.
Where could you find a decimal point?
In whole numbers, a decimal follows the number. Example, in the number 7, the decimal is after it, 7.0 The decimal is not visible, but it is there.
In a decimal number how do you find what digit in the hundreds place?
The third digit to the left of the decimal point is the hundreds place.
Find decimal notation 0.71 percent?
To convert a percent to a decimal, express the percent as a decimal then move the decimal point to the left two places:0.71% = 0.0071
Find decimal notation for .23 percent?
To convert a percent to a decimal, express the percent as a decimal then move the decimal point to the left two places:0.23% = 0.0023
Find decimal notation of 500 percent?
To convert a percent to a decimal, express the percent as a decimal then move the decimal point to the left two places:500.0% = 5.00
How can you find a fraction and a decimal on a number line?
Everywhere. Each and every point on a number line is a fraction and also a decimal.
When is it easiest to find a percent of a number using a decimal?
Always. To convert a decimal to a percentage, all you need to do is to move the decimal point two places to the right.
How do you find the sum of decimal numbers?
You align their decimal points. Sum the numbers as normal and, in the answer, place the decimal point so that it lines up with those of the summands.
What is use when dividing decimals to remove the decimal from the divisor?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. So all the whole numbers that we normally use are decimal numbers - because we usually count in units and tens (and hundreds, thousands, and so on). A decimal representation does not require a decimal point. The question concerns decimal fractions rather than decimal numbers.Mathematically, removing the decimal point and fractional representation makes no difference. Some people find it easier to determine the position of the decimal point in the quotient if the denominator is not a decimal fraction. That is all!
