To eliminate the decimal in the denominator of a fraction, you can multiply both the numerator and the denominator by a power of 10. This is done to convert the denominator into a whole number.
For example, if you have the fraction 1.5/0.5, the denominator is 0.5, which is a decimal. To eliminate the decimal, you can multiply both the numerator and the denominator by 10. Here’s how it works:
- Multiply the numerator: 1.5 x 10 = 15
- Multiply the denominator: 0.5 x 10 = 5
Now your fraction looks like this: 15/5. Since you’ve eliminated the decimal in the denominator, you can simplify the fraction further if needed. In this case, 15/5 simplifies to 3.
In summary, by multiplying both the top and bottom of the fraction by the same power of ten, you can quickly get rid of any decimal in the denominator.
