8 and 12 are both divisible by 4. So: 8/12 divided by 4/4 (meaning the outcome will be the same) is 2/3.
7/98 = 0.0000001626 approx
The least common multiple (LCM) of 8 and 6 is 24.
4
Least Common Multiple (LCM) for 8 7 is 56.
The numerator of the fraction is the decimal number without the decimal point.The denominator is 10 raised to the power which is the number of digits AFTER the decimal point in the original number. Equivalently, it is 1 followed by that number of 0s.Divide both numerator and denominator by their highest common factor (this will have to be a power of 2 or a power of 5).Done.So, suppose you start with 34.5672Numerator = 345672Denominator = 10000So fraction = 345672/10000GCF(345672, 10000) = 8and so simplest form = 43209/1250
7/98 = 0.0000001626 approx

The easiest way that I have found to look at these kinds of problems is as follows:First, we know that 87.5% is just a fancy way of writing 0.875, and we want to get rid of the decimal point and write is a fraction. To do this, we multiply it by 1000 to get 875, but we have to also divide it by 1000 to keep it the same number, so now we have:875/1000From here we can divide by the common factors, and in this case 5 seems to be the most obvious choice. So divide top and bottom by 5 to get:175/200Rinse and repeat to get:35/40Once more to get:7/8And there we have 87.5% as a fraction in lowest terms (simplest form).
