The mass of the two motors is 46 kg. The mass of one of them is 2 2 \ 7 times greater than the other. Find the mass of each motor.
Let’s denote the mass of one motor x kilogram, then the mass of the other motor is 2 2/7 times greater and equal to 2 2/7 x kilogram. Let’s make the equation:
x + 2 2 / 7x = 46.
Let’s solve the equation and find the unknown x:
3 2/7 x = 46.
x = 46: 3 2/7.
x = 14 kilograms.
The mass of one motor is 14 kilograms, then the mass of the second motor is:
2 2/7x = 2 2/7 * 14 = 32 kilograms.
The mass of the second motor is 32 kilograms.
Answer: the mass of the first motor is 14 kilograms, and the mass of the second motor is 32 kilograms.
