Answer: 9 over 12 is = 15 over x
Step-by-step explanation:
Answer:
This is my answer is
Force=mass × acceleration.
120=mass × 2.
120=2m.
mass=60kg
So there are 8 students, therefore each student gets 1/8 of
the cake.
Since only 3/4 of a cake is available, they will each get
1/8 of 3/4.
We can find this by
multiplying 1/8 and 3/4.
To get the answer, we multiply the numerators together and
the denominators together which gives us:
(1*3)/(8*4) = 3 / 32 = 0.09375
So each student only get 3 / 32 of the cake.
