Answer:
12
Step-by-step explanation:
Let the total number of donuts in the pack be x.
Amy = 2/3x
Anna = 1/4x
David = 1
x - 2/3x - 1/4x = 1
Find common denominators for 2/3 and 1/4
The common denominator is 12
2/3 * 4/4 = 8/12
1/4 * 3/3 = 3/12
x - 8/12x - 3/12x = 1
x - 11/12x = 1
1/12x = 1
x = 12
You can always check
Amy = 8
Anna = 3
So David must equal to 1
Hope this helps :)
Have an awesome day!
Answer:
8/12
Step-by-step explanation:
Hope it’s right
You could wash 75 cars at this rate because 45/3 equals 15. You would multiply 5 by 15 and get 75.
Volume of water in the glass = 3 x 2 x 4 = 24 cubic cm.
Volume of water plus the ring = 3 x 2 x 4.25 = 25.5 cubic cm.
Subtract the total with the ring from just the water:
25.5 - 24 = 1.5 cubic cm
