Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Evaluate the division 400:2013400 : \frac{20}{13}.
  • Step 2: Subtract 12 from the result obtained in Step 1.
  • Step 3: Subtract the entire result from 35.

Now, let's work through each step:
Step 1: Evaluate the division 400:2013400 : \frac{20}{13}. Division by a fraction is the same as multiplying by its reciprocal, so we have:
400×1320=400×1320=520020=260 400 \times \frac{13}{20} = \frac{400 \times 13}{20} = \frac{5200}{20} = 260

Step 2: Now subtract 12 from 260:
26012=248 260 - 12 = 248

Step 3: Finally, subtract the result from 35:
35248=213 35 - 248 = -213

Thus, the solution to the problem is 213 -213 .
