The
temperature which has best degree of precision would actually be the
temperature reading which has similar decimal place with the error. So the best
answer would have 1 decimal and from the choices given above, this would be:
16.0°C

Step-by-step explanation:
I don't know if the first set of numbers is all in one set, but I'll do my best to give you an answer.
Really all you need to do is use PEMDAS for the first question.
(Parentheses, exponents, multiply, divide, add, subtract. In that order)

Then to simplify that fraction next to it, notice that 0.018 is 3x 0.06.
that's a 3:1 ratio, so it ends up simplifying to this:

Lastly, to solve the division of that fraction. If you divide by a fraction, you multiply whatever it's dividing by its inverse.
So...

180- 86 = 94
degrees of pizza did I give to you = 94
2.0 w-1.1
2.3 w -3w = 2.0 w , -7+8.1 =1.1
