How many grams are there in 0.258 tons? Round your answer to one decimal place.

One metric ton is equal to 1000000 grams. And we want to know how many grams are there in 0.258 tons. So we can set up a proportion and solve. We know there are 0.258 tons. And we want to know the number of grams. So now we can cross-multiply and solve.

We have 𝑥 times one ton is equal to 0.258 tons times 1000000 grams. So we need to solve for 𝑥. So let’s go ahead and divide both sides of the equation by one ton. It cancels on the left-hand side. And the unit of tons cancels on the right-hand side. So we have that 𝑥 is equal to 0.258 times 1000000 grams, which is equal to 258000.0 grams. And this would already be rounded one decimal place. So this is our final answer.
