Adump truck brought 1/3 of a ton of rock on the first trip, 1/2 of a ton on the second trip, and 4/5 of a ton on the third trip. what was the total weight of the rock?

We'll have to convert the denominators to a number that each of these three will add in to.

We'll use 30, since we can use 15 as we have a denominator of 2.

1/3 = 10/30

4/5 = 24/30

1/2 = 15/30

Now, we just add all the numerators

49/30

1 and 19/30

19 does not evenly divide into anything.

You answer is 49/30, or 1 and 19/30

step-by-step explanation:

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
