Form a ratio and multiply both parts of the ratio by 4/3 to turn the "3/4" into "1" (to represent 1 full driveway) $\Large \frac{2}{3} \ \text{ton} \ : \frac{3}{4} \ \text{driveway}$ $\Large \color{red}{\frac{4}{3}*}\frac{2}{3} \ \text{ton} \ : \color{red}{\frac{4}{3}*}\frac{3}{4} \ \text{driveway}$ $\Large \frac{4*2}{3*3} \ \text{ton} \ : \frac{4*3}{3*4} \ \text{driveway}$ $\Large \frac{8}{9} \ \text{ton} \ : \frac{12}{12} \ \text{driveway}$ $\Large \frac{8}{9} \ \text{ton} \ : 1 \ \text{driveway}$ So we need $$\Large \frac{8}{9}$$ of a ton of gravel.
