Substitution: Total fodder = 297×18297 \times 18

Calculation: 297×18297 \times 18 = 297 × (20 - 2) = 297×20297 \times 20 - 297×2297 \times 2 297×20297 \times 20 = 5940 297×2297 \times 2 = 594 5940 - 594 = 5346

Answer: 5,346 kg of fodder is needed to feed 297 cows every day.

Explanation

This is a multiplication word problem with larger numbers. Total fodder = number of cows × fodder per cow: 297×18297 \times 18 = 5,346 kg.

Solution Steps

  1. Step 1: Identify the operation: 297 cows × 18 kg fodder per cow

  2. Step 2: Calculate: 297×18297 \times 18 = 297 × (20 - 2) = 297×20297 \times 20 - 297×2297 \times 2

  3. Step 3: 297×20297 \times 20 = 5940, 297×2297 \times 2 = 594

  4. Step 4: 5940 - 594 = 5346 kg
