Q. The value of

x

is decreased by

70 \%

. Which expression represents this situation?

\newline

70 x

\newline

0.93 x

\newline

0.3 x

\newline

0.7 x

Calculate $70$ % of the value: To decrease a value by $70$ %, you subtract $70$ % of the value from the original value. The expression for $70$ % of $x$ is $0.7x$ .
Subtract $70$ % from original value: To represent a decrease by $70$ %, you subtract $0.7x$ from $x$ , which is $x - 0.7x$ .
Combine like terms: Simplify the expression $x - 0.7x$ by combining like terms. This results in $0.3x$ .
