Which of the following is a true statement? 9/12 • 12/9 = 0

3/10 ÷ 7/9 = 3/10 • 9/7

4/5 • 4/5 = 1

1/2 ÷ 1/2 = 1/4

3/10 ÷ 7/9 = 3/10 * 9/7

Step-by-step explanation:

Evaluate both sides you get 27/70 = 27/70

3/10 * 9/7 = 27/70

3/10 * 9/7 = 27/70

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
