Step-by-step explanation:
to solve a problem like this you need to set up a proportion
45% is a percent(obviously) so you put 45 over 100 because percent's are fractions of 100
the key word is the word is. i don't kow about anyone else but i was taught is over of(is/of)
this means 27 is the numerator
27/x=45/100
