Best ResponseYou've already chosen the best response.0If 2 over 3 ton of gravel covers 3 over 4 of a driveway, how many tons of gravel are required to cover the entire driveway?

Best ResponseYou've already chosen the best response.1Are you given the length of the driveway?

Best ResponseYou've already chosen the best response.1Oh, no need for this length..... t ton of gravel ddriveway \(\large\color{black}{ \displaystyle \frac{2}{3}t=\frac{3}{4}d }\)

Best ResponseYou've already chosen the best response.1So, you need to solve for d.

Best ResponseYou've already chosen the best response.0yes that is correct

Best ResponseYou've already chosen the best response.1(multiply both sides times 4/3) \(\large\color{black}{ \displaystyle \frac{2}{3}t\color{red}{\times \frac{4}{3}}=\frac{3}{4}d\color{red}{\times \frac{4}{3}} }\)

Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle \frac{2}{3}t=\frac{3}{4}d }\) in this proportion, t is tons of gravel, and d is the driveway. \(\large\color{black}{ \displaystyle \frac{2}{3}t\color{red}{\times \frac{4}{3}}=\frac{3}{4}d\color{red}{\times \frac{4}{3}} }\) i multiplied times 4/3 to isolate the d (the driveway), because you have to find the number of tons of gravel per a driveway. \(\large\color{black}{ \displaystyle \frac{2}{3}t\color{red}{\times \frac{ 4}{3}}=\frac{\cancel3}{\bcancel4}d\color{red}{\times \frac{\bcancel 4}{\cancel3}} }\) 4's and 3's cancel. \(\large\color{black}{ \displaystyle \frac{2}{3}t\color{red}{\times \frac{ 4}{3}}=d }\) and then multiply the fractions \(\large\color{black}{ \displaystyle \frac{2}{3}\times \frac{ 4}{3} \times t=d }\) \(\large\color{black}{ \displaystyle \frac{2\times4}{3\times3}t=d }\)

Best ResponseYou've already chosen the best response.1and then what do you get? (how many tons of gravel, t, do you need, in order to cover the driveway, d?)

SolomonZelman

Best ResponseYou've already chosen the best response.1so you need 8/9ths tons of gravel to cover a driveway
