The perimeter of the triangle is 1.24 m. One side is 4.3 dm, and the other is one whole two-thirds

The perimeter of the triangle is 1.24 m. One side is 4.3 dm, and the other is one whole two-thirds of a cm shorter than the first. Find the length of the third side.

Let’s solve this task by actions:
1) 4.3 dm = 43 centimeters – the length of the first side in centimeters;
2) 43 – 1 2/3 = 42 3/3 – 1 2/3 = 41 1/3 centimeters – the length of the second side of the triangle, since the second side is 1 2/3 centimeters shorter than the first, and the first side is 43 centimeters;
3) 1.24 meters = 124 centimeters – the perimeter of the triangle;
4) 124 – (43 + 41 1/3) = 124 – 84 1/3 = 123 3/3 – 84 1/3 = 39 2/3 centimeters = 119/3: 100 = 119/3 * 1/100 = 119/300 meters is the length of the third side of the triangle.
Answer: 119/300 meters.
