Consecutive means right after each other like 1, 2, 3, 4...so if the first sister is x old, then sister 2 is (x+1) old and sister 3 is (x+2) old. So make an equation that says x+(x+1)+(x+2)=45. Simplify and solve for x (get x alone.)
The answer is four because you solve simplify the equation given and W could equal 4 or -5, and since the width can not be a negative number it has to be 4.
