Two basketball players move in a straight line directly toward one another. Their equations of motion are : x1 = 0.1 m + (-3.4 m/s)t

x2 = -6.3m + (2.9 m/s)t

Which player is moving faster, and what time do the two players collide?

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
