A picture of a goldfish has a scale of 8 centimeters to 3 centimeters.If the actual goldfish is 12 centimeters long,how long is the drawing?

1 answer

Using the given scale of 8 centimeters to 3 centimeters, we can set up a proportion:

Actual length of the goldfish / Length in the drawing = Scale factor

12 centimeters / X centimeters = 8 centimeters / 3 centimeters

Cross multiplying, we get:

12 centimeters * 3 centimeters = X centimeters * 8 centimeters

36 centimeters^2 = 8X centimeters^2

Rearranging the equation, we get:

8X = 36

Dividing both sides by 8, we find:

X = 4.5 centimeters

Therefore, the length of the drawing of the goldfish is 4.5 centimeters.
