When you multiply a decimal by 10 which way does the decimal point move?

Left.


What is a rule for multiplying and Dividing by powers of 10?

Oh, dude, multiplying and dividing by powers of 10 is like the easiest math trick in the book. When you multiply, you just move the decimal to the right as many times as there are zeros in the power of 10. And when you divide, you move the decimal to the left. It's like magic, but with numbers.


What is 100 times 54?

It's 540. The easiest way to multiply 10 or 100 or 1000 or 10000 etc. by a decimal is to look at the number of zeros in the number and move the decimal to the right the same amount of times as the amount of zeros I am multiplying the number by. For instance if I am multiplying 3.5 by 10 I would move the decimal in 3.5 to the right one time because there is one zero in 10. Changing it from 3.5 to 35. If you were multiplying it by 100 you would move the decimal 2 times because there are 2 zeros in 100, with 1000 you would move it three times and so on. If you were dividing it you would do the same thing just move the decimal to the left instead. Hope this information helps you in the future.

What is 50 cents in decimal?

50 cents, exactly as in the question. A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Zeros after the decimal point are inappropriate because they imply a greater degree of precision and there is no justification for that.
