anastassius [24]

Answer:

it is 0.916 (the six is repeated. a line under a number means repeated in this case)

Step-by-step explanation:

First you take 3 1/4 and turn it into 13/4 and turn 2 1/3 into 7/3 and transform those into decimals 13/4 = 3.25 and 7/3 = 2.3 and subtract which is 0.95 plus the fact that the three is repeated which gets your answer of 0.916 however you should say that if they want you to simplify it to two/three decimals, it is 0.95 but if they want it exact it is 0.916 with the six being repeated
