It is: 9/29 times 100/1 = 47.368% rounded to three decimal places

2 over 9 as a decimal = 0.2222 2/9: = 2 ÷ 9 = 0.2222 in decimal

In order to take a number to 2 decimal places, you first consider only the digits that are 2 decimal places in or greater. In this case that would be 2.73. The next step is to asses the thousandths digit. If it is 5, 6, 7, 8 or 9, we round up. Otherwise, we leave the number as it is. In this case, the digit is a 7, so we round up. Thus 2.73762 to 2 decimal places is 2.74

Not exactly. To 2 decimal places, pi is 3.14 To 7 decimal places, pi is 3.1415927 To 9 decimal places, pi is 3.141592654 pi does not terminate - it can be expressed to as many decimal places as required. 3.14 is often used as an approximation when doing calculations as it's easier to work with (than 3.141592653... ).

To work this in your head, make conversions. Twenty percent is 20/100 or .2 and ninety percent is 90/100 or .9, so if we want to multiply, we simply take 2 times 9 and get 18. But we need to account for the two decimal places in the original problem (the .2 and the .9). Move the decimal two places to the left, and 18 becomes .18, so the answer to twenty percent of ninety percent can be found by fairly simple arithmetic.

6.78 x 10-9 in decimal form = 0.00000000678 (move the decimal point 9 places to the left)
