Estimate quotients: word problems

🔢 What is a Quotient?

  • A quotient is the result of division.
  • Example: 12 ÷ 3 = 4 → 4 is the quotient.

🎯 What is Estimation?

  • Estimation means finding an approximate answer, not the exact one.
  • Helps to check answers quickly.

🧮 Steps to Estimate Quotients in Word Problems

Step 1: Read the problem carefully 📖

  • Understand what is being divided and by what.

Step 2: Round the numbers 🔄

  • Round the dividend (the number being divided) and divisor (the number you divide by) to friendly numbers.
  • Friendly numbers: 10, 20, 50, 100…

Step 3: Divide the rounded numbers ➗

  • This gives you an estimated quotient.

Step 4: Check if the estimate makes sense ✅

  • Ask: “Is my answer too big or too small?”

💡 Tips for Word Problems

  • Look for keywords: “shared equally”, “per”, “each”, “divided among”.
  • Use rounding to make division easier.
  • Always compare your estimate with the numbers in the problem.

🌟 Example Problem

  • “There are 98 candies 🍬 and 6 kids 👦👧. How many candies does each get?”
    Step 1: Round 98 → 100, 6 → 5
    Step 2: 100 ÷ 5 = 20
    Estimated quotient = 20 candies per child

📝 Remember:

  • Estimation is not exact.
  • It helps to quickly check answers or make reasonable guesses.
  • Always think about whether your answer is reasonable in the context of the problem.

Learn with an example

🔥 A group of 71 travelers needs to take taxi cabs across the city. If each taxi cab holds 5 people,

Choose the better estimate.

  • 18
  • 14

Divide the number of travelers by the number in each taxi cab.

71 ÷ 5 = ?

Use a compatible number to estimate the quotient.

71 ÷ 5 = ?
70 ÷ 5 = 14

14 taxi cabs is the better estimate.

🔥 A group of 94 golfers wants to rent golf carts. If each cart can hold 6 golfers,

Choose the better estimate.

  • 16
  • 19

Divide the number of golfers by the number in each cart.

94 ÷ 6 = ?

Use a compatible number to estimate the quotient.

94 ÷ 6 = ?
96 ÷ 6 = 16

16 carts is the better estimate.

🔥The town picnic committee has ₹959 to buy watermelons. If each watermelon costs ₹8,

Choose the better estimate.

  • 120
  • 170

Divide the amount of money by the cost of each watermelon.

959 ÷ 8 = ?

Use a compatible number to estimate the quotient.

959 ÷ 8 = ?

960 ÷ 8 = 120

120 watermelons is the better estimate.
