Figure 1 shows an astronaut working with the lunar research module on the surface of the Moon. The mass of the lunar module is 15.000kg. The gravitational
field strength of the Earth is 10N/kg.

The weight of the lunar research module on Earth is 150.000 N

Explanation:

The given parameters for the mass of the lunar module are;

The mass of the lunar moon, m = 15.000 kg

The gravitational field strength of the Earth, g = 10 N/kg

The weight, 'W', of the lunar research module on Earth is given as follows;

W = m·g

Substituting the known values, we get;

W = 15.000 kg × 10 N/kg = 150.000 N

The weight of the lunar research module on Earth, W = 150.000 N.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
