To find what 13 of 15 is, we can interpret this as wanting to know what fraction or percentage 13 represents out of 15. This can be solved simply by dividing 13 by 15.
Mathematically, this is calculated as:
13 ÷ 15 = 0.8667To express this as a percentage, we multiply the result by 100:
0.8667 × 100 = 86.67%This means that 13 is approximately 86.67% of 15. So, if you have a whole of 15 units, 13 units represent about 86.67% of that total.
In everyday terms, if you have 15 objects and you take away some, keeping only 13, you have kept around 87% of the total objects you started with. This calculation is quite useful in various situations, from cooking measurements to budgeting, where understanding proportions is key.
