To solve the problem "What percent 60 of is 45 ?", we can use the formula for calculating percentage:
\[ \text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100 \]
In this case:
- Part = 45 (the amount we want to find the percentage of)
- Whole = 60 (the base that we are using)
Now we can substitute the values into the formula:
\[ \text{Percentage} = \left(\frac{45}{60}\right) \times 100 \]
Calculating the fraction:
\[ \frac{45}{60} = 0.75 \]
Now multiply by 100 to get the percentage:
\[ 0.75 \times 100 = 75 \]
Thus, 45 is 75% of 60.
To summarize:
- Percent = 75%
- Amount = 45
- Base = 60
