i have one more question

Answer 8

to solve
\[ \frac{x}{60}= \frac{3}{5} \]
multiple both sides by 60, like this
\[ 60\cdot \frac{x}{60}= 60\cdot \frac{3}{5} \]
now simplify both sides
(on the left, 60/60 is 1)

Answer 9

60 x 60 is 3600 12 x 60 is 720

Answer 10

the left side is 60/60 * x which is 1*x or just x
now do the right side
