Answer:
He writes [tex]\frac{1}{18}[/tex] manuscripts in 1 hour
Step-by-step explanation:
Let John writes x manuscripts in 1 hour,
So, the number of manuscripts he writes in 12 hours = 12x
According to the question,
[tex]12x=\frac{2}{3}[/tex]
[tex]x=\frac{2}{36}[/tex]
[tex]\implies x=\frac{1}{18}[/tex]
Hence, he writes [tex]\frac{1}{18}[/tex] manuscripts in 1 hour.
