Joe has 0.4 of a black forest cake, which is 14 slices of the cake, left. How many slices of cake were there originally?

35 slices originally

Step-by-step explanation:

1. 0.4 means 40%

2. if 14 slives equal 40% we need to divide by 4 to find 10%

3. 14 divided by 4 is 3.5

4. then we multiply 3.5 (10% of the cake) by 10 because 10•10=100(%)

3.5•10 equals 35 slices

1/5^2 = 7.56/45
