Move the decimal point to the right one time.
if the answer is a three digit answer then make sure there is two numbers on the left and one on the right of the decimal pointthe decimal point will remain in the answer given eg 2.2 * 8 = 17.6
Often, yes. But it depends on the numbers. For example, if you multiply 1.5 x 2, you get 3 as the answer (whole number). But if you multiply 1.5 x 3, you get a decimal of 4.5
Fraction refers to the amount to the right of the decimal point (amounts of less than 1), so if you multiply any (positive) number by a fraction its value will be reduced.
you multiply by 2
You usually get another number!
Move the decimal point to the right one time.
It moves three places to the right.
Assuming the number is represented by a decimal integer, initialise a counter to zero, then repeatedly divide the number by 10 and until the number is zero. After each division, examine the remainder. Each time the remainder is zero, increment the counter. If the number is represented by a decimal float, repeatedly multiply by 10 until the value is an integer, then perform the previous algorithm.

whenever you multiply a whole number by a decimal you get a decimal. 2.9x100=290
Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
you multiply by 2
True
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
