Question 25 of 44intermediate🔧 ApplyNumerical3 marks

A dairy farm has many cows. Chippi the lizard is surprised to see 88 legs. How many cows are there in the farm?

Correct Answer

Given: Total legs = 88, Legs per cow = 4

Formula: Number of cows = Total legs ÷ Legs per cow

Calculation: 88 ÷ 4 = 22

Answer: There are 22 cows in the farm.

Partial Quotient Method: Step 1: 40 legs = 10 cows (88 - 40 = 48 legs left) Step 2: 40 legs = 10 cows (48 - 40 = 8 legs left) Step 3: 8 legs = 2 cows (8 - 8 = 0 legs left) Total: 10 + 10 + 2 = 22 cows

Explanation

The chapter applies division to find the number of cows. Each cow has 4 legs. Total legs = 88. Number of cows = 88 ÷ 4 = 22 cows. Using partial quotients: 40 legs for 10 cows (88-40=48 left), 40 legs for 10 more cows (48-40=8 left), 8 legs for 2 cows (8-8=0 left). Total cows = 10+10+2 = 22.

Solution Steps

  1. Step 1: Each cow has 4 legs

  2. Step 2: Number of cows = 88 ÷ 4

  3. Step 3: 40 legs = 10 cows (88-40=48 legs left)

  4. Step 4: 40 legs = 10 cows (48-40=8 legs left)

  5. Step 5: 8 legs = 2 cows (8-8=0 legs left)

  6. Step 6: Total cows = 10+10+2 = 22 cows
