As part of an enterprise day, Guramar and Gurnam baked 4 cakes. They gave 1/2 of one cake away to the staff. In the morning they sold 2 1/3 cakes and in the afternoon they sold 1 1/8. How much cake did they have left? ​

9514 1404 393

  1/24 of a cake

Step-by-step explanation:

The remaining amount of cake was ...

  4 -1/2 -2 1/3 -1 1/8 = 4 -12/24 -2 8/24 - 1 3/24 = (4 -2 -1) -(12 +8 +3)/24

  = 1 -23/24 = 1/24

1/24 of a cake was left

Equation: 

When adding or subtracting, you have to make sure they have a common denominator

So you have to multiply  by 



Since they both have the same denominator, you subtract



One thing to note is when subtracting, you DO NOT subtract the denominator, only the numerators

To reduce to the lowest terms, you need to find a common factor.
5 goes into 10 two times and goes into 15 three times

 ÷ 

 ÷ 

That leaves it with the fraction
