Question 1103428: Convert the following to fractions: 0.4321, 0.45, and -181.3
Answer by math_helper(2461) (Show Source): You can put this solution on YOUR website!

a) 0.4321
Notice that if you multiply by 10000, the decimal point will move 4 places to the right, making 0.4321 into an integer. We then just write the 10000 as the denominator:
0.4321 = 4321/10000
Now we should check if the fraction can be reduced. Since there are
no common factors (4321=29*149 and 10000 = (2*5)^4) the fraction is already reduced.
