Hey there!

and $\frac{5}{8}$ equals $2\frac{5}{8}$

and $\frac{2}{3}$ equals $2 \frac{2}{3}$

So, now that we got that out of the way, let's set up our problems to answer your question, shall we?

$2\frac{5}{8} = \frac{21}{8} = 2.625\\ \\ \\ 2\frac{2}{3} = \frac{8}{3} = 2.67$

$2\frac{5}{8} \ \textless \ 2\frac{2}{3}$

The greatest (aka the biggest one) is $2\frac{2}{3}$

Good luck on your assignment and enjoy your day!

Let's convert the mixed fractions to "improper" firstly, and then let's make them the same denominator by multiply each other by "the other's denominator", so

$\bf \stackrel{mixed}{2\frac{5}{8}}\implies \cfrac{2\cdot 8+5}{8}\implies \stackrel{improper}{\cfrac{21}{8}}
\\\\\\
\stackrel{mixed}{2\frac{2}{3}}\implies \cfrac{2\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{8}{3}}\\\\
-------------------------------\\\\
\cfrac{21}{8}\cdot \cfrac{3}{3}\implies \boxed{\cfrac{63}{24}}\qquad \qquad \qquad \qquad \qquad \qquad \cfrac{8}{3}\cdot \cfrac{8}{8}\implies \boxed{\cfrac{64}{24}}$

so, which one do you think is greater?

1) a: [$]75 + [$]0.20x = ƒ(m) b: [$]0.35x = ƒ(m)the 75 is how much you automatically pay and the .2x and .35x is how much you would pay per mile (the variable can be changed to your liking). ƒ(m) is the total cost. 2) set your equations to equal each other.75 + .2x = .35xsolve.move the .2x over by subtracting it from both sides. 75 = .15xget x by itself by dividing both sides by 0.15.500 = xit would take 500 miles for plan a and b to be equal in cost.
