Q. What is the result when the number

75

is decreased by

5.4 \%

?

\newline

Answer:

Calculate Percentage of Original: To find the value after a decrease by a percentage, we need to calculate the percentage of the original number and then subtract it from the original number. $\newline$ First, we calculate $5.4\%$ of $75$ . $\newline$ $5.4\%$ of $75$ = $(5.4/100) \times 75$
Perform Calculation: Now, we perform the calculation: $\frac{5.4}{100}$ * $75$ = $0$ . $054$ * $75$
Find Amount to Decrease: Next, we multiply $0.054$ by $75$ to find the amount to decrease from the original number: $\newline$ $0.054 \times 75 = 4.05$
Subtract Decrease from Original: Finally, we subtract the decrease from the original number to find the final value: $\newline$ $75 - 4.05 = 70.95$
