One harvester threshed 231 tonnes of grain, and the second harvested 46 tonnes less.

One harvester threshed 231 tonnes of grain, and the second harvested 46 tonnes less. How much grain did both harvesters thresh?

Let’s calculate how many tons of grain were threshed by the second harvester. Let’s subtract from the amount of grain that the first harvester threshed – 231 tons 46 tons:

231 – 46 = 185 tons.

The second harvester threshed 185 tons of grain.

Let’s calculate how much grain was threshed by two combines together. Let’s summarize the amount of grain that the first harvester threshed – 231 tons and the amount of grain that the second harvester threshed – 185 tons:

231 = 185 = 416 tons.

Both harvesters threshed 416 tons of grain.

Answer: both harvesters threshed 416 tons of grain.
