Okay. So, to have some estimates, let's round each of them to the nearest whole number. -3 4/5 rounds to -4 and -5.25 rounds to -5. -4 + -5 = -9. Now, let's add the numbers in their actual form. -3 4/5 is -3.8 in decimal form. -3.8 - 5.25 is -9.05 or -9 1/20 in simplest fraction form. A reasonable estimate is -9 and the actual answer is -9 1/20. The answer is A.
