Please exlain how I "use the power of ten to change each to a decimal". I was in a band lesson when my math teacher taught this. Thanks.
4 over 50 9 over 25
(fractions)
4/50= 0.08=8.0*10(exponent-2),exponent-2 means to move the decimal point to the left 2 spaces..
9/25=0.36=3.6*10(exponent-1),the same as the first one, exponent -1 means to move the decimal point to the left 1 space...
to represent exponents in typing, put ^#
your on your own kid
ok
To convert fractions to decimals using the power of ten, you need to follow these steps:
Step 1: Write down the fraction you want to convert.
Step 2: Determine the power of ten needed to change the fraction to a decimal. The power of ten is determined by the denominator of the fraction. For example, if the denominator is 50, the power of ten is -2 (since you need to move the decimal point two places to the left to convert the fraction to a decimal).
Step 3: Multiply the numerator of the fraction by the appropriate power of ten. In this case, multiply the numerator by 10^-2 (which is 0.01 since 10^-2 means to move the decimal point two places to the left).
Step 4: Simplify the result. In this case, calculate 4 * 0.01 = 0.04. This is the decimal representation of the fraction 4/50.
Step 5: Repeat steps 2-4 for each fraction you want to convert.
So, for the fraction 4/50, the decimal representation is 0.04.
For the fraction 9/25, the power of ten is -1 (since you need to move the decimal point one place to the left), and the calculation would be 9 * 0.1 = 0.9. So, the decimal representation of 9/25 is 0.9.
Remember, the power of ten (exponent) is determined by the denominator of the fraction, and you move the decimal point to the left to convert the fraction to a decimal.
