Answer:
first choice in the image.
numerator: 12
denominator: 30
Explanation:
"Name the numerator and denominator of the fraction that represents the number of trucks that he has loaded out of the total needing to be loaded"
so numerator = "number of trucks that he has loaded"
and denominator = "total needing to be loaded"
Joaquin was asked to load 30 trucks today. So his/her total would be 30.
thus the denominator is 30.
Joaquin has finished loading 12 already, which means he/she has loaded 12. so, the numerator is 12.
