The scale drawing of a poster design has the dimensions of 15 cm by 20 cm. the dimensions of the actual poster will be 60 cm by 80 cm. what is the scale of the drawing? 1/15 1/4 1/3 3/4

The scale is 1:4, as the poster's dimensions are 4 times larger than the scale drawing, which is represented by the second number in the ratio. To see this, you need to see that 15 goes into 60 four times and 20 goes into 80 four times. I hope this helped you!
