The answer is 1.83
you look to the number after the hundreds place which is 5. the rule is that is that place is 5 or more then you can round up with the hundreds place which turned the 2 into a 3
It would be 13... if I did my math right.
/ means divide, so U( an unknown value ) / 6 = 9. to get the answer, simply multiply 6 x 9
