Question

There are approximately 39.97 inches in 1 meter. How many meters are there in 240 inches

Answer 1

1/39.97=x/240
x= 6

about 6 meters

Answer 2

You can cross multiply. 
1/39.97 = x/240
39.97x = 240 times 1
 39.97x = 240
 divide each side by 39.97
39.97x/39.97 = 240/39.97
 dividing 39.97 to itself crosses it out,
so your left with x = 6 
so, 6 meters
