the answer would be 5.344. First you start with the division using order of operations
(i will be rounding to the nearest thousandth. Ex. 1.3337--->1.334)
(48/19)-(-31/11)= (2.526)-(-2.818)
and now you take away the negative 2.818 , which when taking away negatives is exactly like adding, so if you want you can change the minus sign too a plus sign and make negative 2.818 become a positive number (new equation: 2.526+2.818)
2.526--2.818=5.344.
