150 students voted in a school election. 12% voted for uzair. how many votes was this?

First you must make the percentage a usable number for the setup to do so...

You'll move the . over two times getting .12

Now you'll multiply 150 by .12 resulting in the setup 150(.12)

18

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
