84 is 42 percent of what number

Question 1

Question 2

$\text{Hey there!}$

$\text{84 is 42\% of what number?}$

$\mathsf{Let\ x\ be\ the\ unknown\ number}$

$\mathsf{42\%=(42)/(100)}=(42/2)/(100/2)=(21)/(50)$

$\mathsf{Simply\ both\ sides\ of\ the\ equation!}$

$\mathsf{(21)/(50)x=84}$

$\mathsf{MULTIPLY\ both\ sides\ by\ (50)/(21)}$

$\mathsf{(50)/(21)*(21)/(50)x=(50)/(21)* 84}$

$\mathsf{Cancel\ out: (50)/(21)*(21)/(50)\ because\ it\ gives\ you\ 1}$

$\mathsf{(50)/(21)*84\ because\ it\ SHOULD\ give\ you\ your\ answer}$

$\mathsf{If\ you\ solved\ correctly\ you\ should\ have\ found\ your\ answer!}$

$\checkmark\mathsf{\underline{x=200}}\checkmark$

$\boxed{\boxed{\mathsf{Thus\ your\ answer\ is: 200}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day}!$
