Answer: -5/4
Explanation: The number marked by the dot is 1.25. To convert decimals to fractions, think of it as a percent. 1.25% is like 125% (out of 100%) so that would be 125/100. Then divide by GCD (greatest common divider). GCD must be a multiple of both 125 and 100. The GCD in this case is 25. So divide numerator (125) and denominator (100) by 25 to get 5/4. Hope this helps :)
