You could try estimation to get an idea of the magnitude of the answer.
It doesn't really. If you are a competent user of arithmetic operations on decimal numbers then this will only mean additional calculations simply to confirm something which you would have done correctly anyway. And if you are not competent, then who is to say that your estimation is more likely to be correct?
i dont know
The decimal that's greater is .57 because it has the least amount of numbers.
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
"You have to count the spaces to the right to know how many spaces you have to put."
The number 1.5 belongs to the set of real numbers, specifically to the subset of real numbers known as rational numbers. Rational numbers are numbers that can be expressed as a ratio of two integers, in this case, 3/2. Additionally, 1.5 can also be classified as a decimal number, specifically a terminating decimal, as it ends after a finite number of decimal places.
There are infinite numbers between those two numbers... But if you wanna know numbers that only have two decimal places, then they are 4.32 and 4.33
If two numbers, P and Q, have x and y digits after the decimal point respectively, then P*Q has (x+y) digits after the decimal point.
i really dont know. figure it out or ask a math geek
Decimal is mainly used in trade or to buy things . Even the gas pump shows two set of decimal numbers . Decimal numbers are commonly used in areas like finance , medicine and construction when measuring units like currency , mass and distance .
Since there are an infinite number of decimal numbers, it is impossble to know what the next number in the sequence will be. Rounded to a single decimal place, -0.9 + 0.1 = 0.8.
writing percents always depends on what you are taking the percent of. If you are trying to find the percent of 1.97 out of 100 then it is 1.97% If you have any two numbers and you want to know the percent, you divide the numbers and the answer will give you a decimal. You then take that decimal and move the decimal place over to spots to the right and that is your percent.
