To get 3 5/6 - 4 5/12, you would have to get the denominators even. So 12 is the lowest, so lets use that.
3 5/6 - 4 5/12
3 10/12 - 4 5/12
3-4= -1
10-5= 5
Now, you have a -1 and a + 5/12, to do this you have to turn -1 into -12/12
-12/12 + 5/12 = -7/12
Your answer is -7/12
Hope this helped!
Answer:
Step-by-step explanation:
One of the cars are blue. it can travel 31 1/2 miles on 1 1/4 gallons of gasoline. Converting 31 1/2 miles to decimal, it becomes 31.5 miles. Converting 1 1/4 gallons of gasoline to decimal, it becomes 1.25 gallons of gasoline.
Therefore, the miles per gallon for the blue car is
31.5/1.25 = 25.2 miles per gallon.
Another car is red it can travel 28 4/5 miles on 4/5 gallon of gasoline.
Converting 28 4/5 miles to decimal, it becomes 28.8 miles. Converting 4/5 gallons of gasoline to decimal, it becomes 0.8 gallons of gasoline.
Therefore, the miles per gallon for the red car is
28.8/0.8 = 36 miles per gallon.
The answer is 10.6 units .....
So you have 175 guests. = 175gst
1 cheeseck= 12 gst
Set up you ratio so that your units cancel.
175gst x 1 cheese c
----------------
12 gst
Here the gst cancel and you are left with cheese cake so
175/12 = 14.58 or 15
