Question

Some frilled lizard grow to be 90 centimeter long . if 2 /3 of this length is its tail , how long is the tail.

Answer 1

To get the answer of this, we need to multiply 2/3 by 90 centimeters to get 2/3s of the total length. Sometimes it is easier to just think, "what is a third of 90?" and then double it, but the foolproof way to get the answer is to multiply the fraction by 90/1.

2/3 * 90/1 = 180/3. Divide out and the answer is:

60 centimeters
