Answer:The fraction of the cupcakes that Ron have left to take home is 3/8
Step-by-step explanation:
Let x represent the total amount of cupcakes that Ron brought to school. By the end of the day, 5/8 of the cupcakes were gone. This means that the total mount of cupcakes that Ron had already shared is 5/8 × x = 5x/8.
The amount of cupcakes left would be x - 5x/8 = (8x - 5x)/8 = 3x/8
The fraction of the cupcakes that Ron have left to take home would be the amount that he has left divided by the initial amount. It becomes
(3x/8)/x = 3x/8 × 1/x = 3/8
