The perimeter of the triangle is 1.25 m. One side is 4.3 inches, and the other is 1 2/3 cm

The perimeter of the triangle is 1.25 m. One side is 4.3 inches, and the other is 1 2/3 cm shorter than the first. Find the length of the third side and express it in meters.

The perimeter is the sum of its three sides. Let’s convert all units to centimeters.
1.25 m = 125 cm; 4.3 dm = 43 cm.
1) What is the length of the second side of the triangle?
43 – 1 2/3 = 42 3/3 – 1 2/3 = 41 1/3 (cm)
2) What is the sum of the first and second sides of the triangle?
43 + 41 1/3 = 84 1/3 (cm)
3) What is the length of the third side of the triangle?
125 – 84 1/3 = 124 3/3 – 84 1/3 = 40 2/3 (cm)
To convert centimeters to meters, you need to divide the number of centimeters by 100 (since 1 m = 100 cm)
40 2/3: 100 = 122/3: 100 = 122/300 (m) = 61/150 (m)
Answer. 61/150 m.
