70 = 7,000% (decimals are converted to percent by multiplying x 100).
All decimals can be converted to percent by multiplying them by 100: 2.2 x 100 = 220%
Yes, that is correct. Decimals are converted to percent by multiplying by 100 (2.4 x 100 = 240).
10.0 x 10.0 = 100.0 1pl + 1pl = 2 pls - -- -- -- -- -- 10.0 x 10.0 x 10.0 = 1000.0 1pl + 1pl + 1pl = 3pls and so on.
Lets say that u r doing the problem. 5.2 x 2.1 there are altogether 2 numbers to the right of the decimal, so you take out the decimals, multiply, and add the decimal 2 numbers to the left.

Multiplying decimals: Example: 2.5 x 1.3 = 3.25 Start by removing the decimal points, thus: 25 x 13 = (the answer is 325) Both 2.5 and 1.3 have 1 decimal places, so 1 + 1 = 2 (decimal places) Counting 2 places, right to left, places the decimal point here: 3.25 Search Google for division of decimals - there are plenty of how to examples and help on the internet!
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.
10.0 x 10.0 = 100.0 1pl + 1pl = 2 pls - -- -- -- -- -- 10.0 x 10.0 x 10.0 = 1000.0 1pl + 1pl + 1pl = 3pls and so on.

If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.
.004 x 500 = 2
If two decimal number have X and Y decimal places, respectively, then the raw product (before removing any trailing zeros) of the two numbers will have (X + Y) decimal places.
There are many ways to figure 2.5x2.5. If the decimals confuse you, remove the decimals and you may insert them at the end. 25x25=625.Remember*: When multiplying vertically, don't insert the decimal under the decimals in the factors:2.5 Instead, move the decimal two places to the left since therex2.5 are two decimals (one in each factor)____ so that the answer is 6.25.62.5 Not correct.
x = .4% * 20 x = .004 * 20 x = .08.
