Answer:
11/20
Step-by-step explanation:
We can visualize the cake as being something that has a mass. Let’s say the mass of the cake is 100g.
4/5 was left, this means 4/5 of 100 was left which is 80g
Now, brain ate some leaving 1/4 of the cake. This means what was left is 1/4 of 100 = 25g
Now, we know that brain ate from 80g to 25g. The amount ate by brain is 80g -25g = 55g
Now, the fraction ate by brain is 55/100 = 11/20
If you would like to divide 2/3 by 1/2, you can do this using the following step:
2/3 / 1/2 = 2/3 * 2/1 = 4/3 = 1 1/3
The correct result would be 1 1/3.
It has a ratio of 1:4, meaning for every x, you'd get 4 from your y
52 ten cent coins, and you have 36 five cent coins.
Their sum is 700 cents which is equal to 7 dollars.
