One side of the triangle is 6 cm. The second side is 2/3 the length of the first side

One side of the triangle is 6 cm. The second side is 2/3 the length of the first side and the third side is 0.75 of the first side. Find the perimeter of the triangle.

Find the length of the second side of the triangle.
In our case, 6 centimeters represents 1 whole or 3/3.
To find the value 2/3, divide the whole value by the denominator of the fraction, and then multiply by the numerator:
6 centimeters: 3 * 2 = 4 centimeters.
Let’s find the third side.
We write 0.75 integers in the form of a regular fraction and reduce as much as possible:
75/100 = 3/4
Thus, 6 centimeters of the first side represent 4/4 of a fraction.
We divide this value by the denominator of the fraction and multiply by the numerator, just as in the first example:
6 centimeters = 60 millimeters.
60 millimeters: 4 * 3 = 45 millimeters = 4.5 centimeters.
Now we can find the perimeter of the triangle:
6 centimeters + 4 centimeters + 4.5 centimeters = 14.5 centimeters.
Answer: 14.5 centimeters.
