What is the easiest way to order decimals?
Change them into fractions over 10 or 100 and then order them
What is the next power of 10 after 10 000?
Next power of 10 after 10 000 is 100 000.
What is the next square number after 90?
100 is the next square number (10 x 10)
Why is 100 x 0.1 equals 10 without using the rule of moving the decimals?
You what to understand that 0.1 = 1/10 so you really have.. 100* 1/10 = 100/10 which clearly equals 10 You must not understand the "rules of decimals" yet. Look things over more carefully. For me the rules of decimals says that when you have multiplication, if you move one decimal to the right you must move another decimal to the left by the same amount In your example.. 100 x 0.1 =10 It works because 100 = 100.0 Note when you move a decimal to the right you are effectively multiplying the number by 10, for example... 23.3 x 10 = 233.0 When you move it to the left you are dividing it by 10.... 23.3 /10 = 23.3 ÷ 10 =2.33
What is bigger 0.9 or 0.39?
In mathematics, when comparing decimals, you can think of them as fractions. In this case, 0.9 is equivalent to 9/10, and 0.39 is equivalent to 39/100. To compare them, you can convert them to have a common denominator, which in this case is 100. When both decimals are written with two decimal places, 0.9 is bigger than 0.39 because 0.9 is equivalent to 90/100, which is greater than 39/100.
