A car travels 1/6 of the distance between two cities in 3/5 of an hour. At this rate, what fraction of the distance between the two cities can the car travel in 1 hour? Enter your fraction in the space provided. /
@phi
I would use ratios. distance/ time = distance / time
so then 1/6 / 3/5 = 3/5 / 1/6
Right @phi?
ok on the "left side" on the right side we have "unknown distance" over 1 hour of time so \[ \frac{ \frac{1}{6}}{\frac{3}{5}} = \frac{x}{1}\]
so then...
x is the unknown distance x/1 is just x to simplify. multiply the top and bottom of the "ugly fraction" by 5/3
x/1 * 5/3?
5x/3
you could "cross multiply" (maybe that is what you are trying to do ?) but we want x by itself.. \[ \frac{ \frac{1}{6}}{\frac{3}{5}} = \frac{x}{1} \\ \frac{ \frac{1}{6}\cdot \frac{5}{3}}{\frac{3}{5}\cdot \frac{5}{3}} = x \]
notice that 3/5 * 5/3 is 1 and 1 in the denominator means we can ignore it.
5/18 / 15/15
15/15 = 1 when you divide by 1, you can ignore it , right ?
yes
so that simplifies to 5/18
so then that's the answer??
yes. if we go back to the original ratio, we are saying \[ \frac{ \frac{1}{6}}{\frac{3}{5}} = \frac{\frac{5}{18}}{1} \] in other words: if we go 1/6 of the way in 3/5 of an hour, then we go 5/18 of the way in 1 hour
ok, thx!!!!!!!!!!!!!!!
can u help with another one?
last one
ok :D
