how 1/2x converted into 2x
he cancelled the same numerators and thus got the denominator as equal
u can do one more step here to avoid any confusion is to cross multiply and show in separate step

Hey mate here is ur ans
1/2:1/3::1/5:1/x
we know that the product of extremes is equal to the product of means
so
1/2*1/x=1/3*1/5
=>1/2x=1/15
now cross multiply
=>1*15=1*2x
=>2x=15
so x=15/2=7.5
hope it helps you
