Final answer:
To find what the other 60% represents when 40% equals 1380, first establish the total value by dividing 1380 by 0.40 to get 3450. Then, calculate 60% of this total by multiplying 3450 by 0.60 to find that the other 60% equals 2070.
Step-by-step explanation:
To calculate what the other 60% equals, given that 40% is 1380, we can set up a proportion where 40% corresponds to 1380. We will first find the value of the whole (which represents 100%) and then calculate what 60% of this whole would be.
Step 1: Set up the proportion.
40% corresponds to 1380, so we can write the equation:
0.40 * Whole = 1380.
Step 2: Solve for the whole.
Divide both sides by 0.40 to find the value of the entire amount:
Whole = 1380 / 0.40 = 3450.
Step 3: Now that we have the value of the whole, we can calculate 60% of it:
0.60 * Whole = 0.60 * 3450 = 2070.
Therefore, the other 60% equals 2070.
