The answer is 35/64 or 0.546875 in decimal form
first we write all numerators above the least common denominator 64
1+40-6
————
64
next we solve the numerators by doing 1+40-6 to get 35/64
18* is 18 above 0. -12* is 12 below 0.
So add: 18+12=X. The difference in temperature is X :)
The correct answer is letter C.
The reason is because there are 12 cake donuts out of the 36 total. This is a simple ratio of 1 to 3. This means one out of every 3 people would get a cake donut. If there are 12 people, this is 4 groups of 3, so one person from each group of 3 is 4 people.
2 1/2 + 2. 3/5 = 2. 5/10. + 2 6/10. = 4 11/10 = 5 1/10
