The distance from the Sun to Mercury is two-fifths, and the distance from the Sun to Venus is seven-tenths of the distance

The distance from the Sun to Mercury is two-fifths, and the distance from the Sun to Venus is seven-tenths of the distance from the sun to the earth. Which planet is closer to the Sun Mercury or Venus. Which of the conditions of the problem is to determine the orbit of which of the planets Mercury or Venus is closer to the Earth’s orbit?

1) How much closer is Mercury to the Sun than Venus, if it is known from the problem statement that the distance from the Sun to Mercury is two-fifths, and the distance from the Sun to Venus is seven-tenths of the distance from the Sun to the Earth?
7/10 – 2/5 = 7/10 – 4/10 = 3/10 (the distance from the Sun to the Earth).
2) What is the distance between the orbits of Mercury and Earth?
1 – 2/5 = 3/5 (distance from the Sun to the Earth).
3) What is the distance between the orbits of Venus and Earth?
1 – 7/10 = 3/10 (distance from the Sun to the Earth).
4) How much is the distance between the orbits of Mercury and the Earth greater than the distance between the orbits of Venus and the Earth?
3/5 – 3/10 = 6/10 – 3/10 = 3/10 (distance from the Sun to the Earth).
Answer: the planet Mercury is closer to the Sun than Venus; the orbit of the planet Venus is closer to the orbit of the Earth.
