arianareyesпусть 1,5(6) = Х. Тогда 10 * Х = 15,6(6)
9 * Х = 10 * Х - Х = 15,6(6) - 1,5(6) = 14,1
Х = 14,1 / 9 = 47 / 30
60 * 1,5(6) = 60 * 47 / 30 = 94

помогите перевести On July 2nd 1900 crowds of people living in a German town gathered to watch the very first Zeppelin airship go up in the air. Similar airships had been around for about 50 years but the Zeppelin was the first airship with a special design that allowed it to travel faster than those built before. The Zeppelin's inventor was Count Ferdinand von Zeppelin. In 1910, the airship Deutschland became the world's first commercial airship. By the start of World War I in 1914, German Zeppelins had travelled over 172,000 km and carried over 34,000 passenger and rew safely.
