Finding a Number 30% Less Than 70
To find the number that is $30\%$ less than 70, we first calculate the value of $30\%$ of 70.
Calculate Percentage Reduction
The reduction amount is $30\%$ of 70. This can be calculated as:
Reduction = $\frac{30}{100} \times 70$
Reduction = $0.30 \times 70$
Reduction = $21$
Determine the Final Number
Now, subtract this reduction amount from the original number (70) to find the required number.
Final Number = Original Number - Reduction
Final Number = $70 - 21$
Final Number = $49$
Therefore, the number that is $30\%$ less than 70 is 49.
