Answer:
The truck is hauling 3/4 of a full load
Explanation:
we know that
2/3 ton of gravel represent the 100% of a full load
Find out how much of a full load the truck is hauling with 1/2 ton of gravel, using proportion
Let
x ----> the percentage of a full load
![((2/3))/(100\%)=((1/2))/(x)\\\\x=100\%(1/2)/(2/3)\\\\x=100\%(3/4)\\\\x=75\%](https://img.qammunity.org/2020/formulas/mathematics/high-school/xsd2z1e9eyip8vw7wzdarsbc9yvgbckz3e.png)
Convert to fraction number
![75\%=(75)/(100)=(3)/(4)](https://img.qammunity.org/2020/formulas/mathematics/high-school/bvo4edb172fhprhk1unfx36g7qn2ibk574.png)
therefore
The truck is hauling 3/4 of a full load
