If the number is an integer, (doesn't have a fractional part) take the number and add a zero. Example: 4 x 10 = 40; 365 x 10 = 3650; 60 x 10 = 600
If the number has a fractional part, move the decimal point one place to the right. Example: 6.5 x 10 = 65; 4.25 x 10 = 42.5; 1.666... x 10 = 16.666...
easy you just multiply it by ten or so... EX. 5*.6= 3 and 10*.6= 6
The simplest way is to multiply it by 10. 4.2 * 10 = 42. There are an endless number of ways to do it however.
To convert the number in centimeter to millimeter, multiply the number by 10.As 1 cm = 10 mm.
you could multiply 84 by 10 = 840 then multiply 84 by 2 = 168 add these two numbers = 1008
110 the simplest way to multiply any number by 10 is to add a zero to the end
Move the decimal point, the same number of places as the power of 10. That way ---> to multiply. This way <--- to divide.
The quickest way is to multiply the original number by 0.9
100 square feet. This is an easy calculation - just multiply the length by the width. The answer is the number of square feet.
to multiply a number by 10, all you have to do is add zeros at the end of the number. Below are examples: 10*1=10 10*10=100 10*100=1000
The easier way to find the relationship is to multiply the denominator (bottom or right number) to get one hundred then you must multiply the numerator (top or left number) by the same number and the numerator will be your percentage 1/10 X 10 = 10/100 = 10% Hope this helped :)
You move the decimal the amounts of zeros it has to the right. so if the number is 1.8 x 10= you move the decimal one to the right since it has one zero, then you multiply and get 18.0 its easier with a calculator but its still easy :)
40*52 = 2,080. If you need to calculate this in your head, an easy way is to first multiply 52 by 4 instead of 40. That will give you an answer of 208. Then you can multiply by 10 to get 2,080.
