Step-by-step explanation:
To convert 3 tons and 400 ounces into a single unit, we need to first convert tons to ounces since they are both units of weight.
1 ton = 32,000 ounces
So, 3 tons = 3 * 32,000 = 96,000 ounces
Adding the 400 ounces:
96,000 ounces + 400 ounces = 96,400 ounces
So, 3 tons 400 ounces is equal to 96,400 ounces.
