How 1 half, 1/2 (fraction notation), is written in decimal notation (with 3 decimals) ? 1/2 = 0.500
A simple trick with multiplying decimal numbers is to remove the decimals, multiply the two numbers, then add the decimals back in. The number of decimals you add back in is the total number of decimal places. For example, the stated problem has 1 decimal places in 2.1 and 2 decimal places in 5.01. So first we do the following: 21x501=10521 Now we add 1+2=3 decimal places into the result above: 10.521 That's the answer.
1) multiply as normal 2) count the amount of decimal places in the factors 3) put the same amount decimals in your product or anwser : ) , 8 ) , $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
There are an infinite number of options: 1+1+1+... 200 times 1+1+1+... 198 times +2 1+1+1+... 197 times +3 1+1+1+... 196 times +2+2 1+1+1+... 196 times +4 etc 2+2+2+... 100 times 2+2+2+... 99 times +4 etc Then start with decimals to one place: 1.1+1.1+1.1... 181 times +0.9 etc and then decimals to 2 places, 3 places etc then other rationals (infinitely repeating decimals), and then irrational numbers and, if you are not tired yet, complex numbers.
1/3(.3 repeated), 2/3(.6 repeated), 1/9(.1repeated), 2/9(.2 repeated), etc. There are billions of repeating decimals.
2/3 or two thirds. In decimals, it is 0.666666666 repeating.
Integers are the set of (...-3, -2, -1, 0, 1, 2, 3...) No decimals or fractions.

No. Natural numbers are the positive integers: 1, 2, 3, ...
-3, -2, -1, 0, 1, 2, 3, 4 .... numbers that aren't fractions or decimals, but include negative numbers.
3 5/10 = 3 1/2 = 3.5
A terminating decimal means a decimal with a definite end. For example 1/2 = .50. 3/4 = .75 3/8 = .375 The decimals that don't end or called non-terminating decimals.
