Question 290893
Twice a number divided by 4 is 16
<pre>
Change the words "a number" by N

Twice N divided by 4 is 16

Cange the words "N divided by 4" to {{{N/4}}}

Twice {{{N/4}}} is 16

Change the word "Twice" to "2 times"

2 times {{{N/4}}} is 16

Replace the word "times" with "*"

2*{{{N/4}}} is 16

Replace "2*{{{N/4}}}" by {{{2N/4}}}

{{{2N/4}}} is 16

Replace the word "is" by " = "

{{{2N/4=16}}}

Multiply both sides by 4:

{{{4*(2N/4)=4*16}}}

{{{cross(4)*(2N/cross(4))=64}}}

{{{2N=64}}}
 
Divide both sides by 2

{{{2N/2=64/2}}}

{{{cross(2)N/cross(2)=32}}}

{{{N=32}}}
