Answer: 19/70
Step-by-step explanation: The easiest way to simplify fractions is to find the factors of both the numerator and the denominator (the numbers that multiply to make that number). For example, the factors of 6 would be one and six, along with two and three. An easy way to do this with big numbers is to input the number divided by x into your y equals function on a graphing calculator. Then you can go to the table, and the x and y values will be the factors. Find the factors that are the same between the numerator and denominator, in this case 2, and divide each by that number. Thirty-eight divided by two is nineteen, 140 divided by two is 70. That's your simplified fraction.
