Estimate the Factors and Solve: Which Expression Has an Estimated Product of 60?

In mathematics, estimation is a crucial skill that helps us approximate the value of a quantity or expression. It is an essential tool for problem-solving, as it allows us to make educated guesses and check our answers. In this article, we will explore how to estimate the factors of an expression and solve for the product. We will use this skill to determine which of the given expressions has an estimated product of 60.

What is Estimation in Mathematics?

Estimation in mathematics involves approximating the value of a quantity or expression by using mental math or simple calculations. It is a way of making an educated guess about the value of a quantity, based on the information given. Estimation is an essential skill in mathematics, as it helps us to:

  • Check our answers
  • Make educated guesses
  • Approximate values
  • Solve problems quickly

How to Estimate Factors

To estimate the factors of an expression, we need to follow these steps:

  1. Round the numbers: Round the numbers in the expression to the nearest whole number or to one decimal place.
  2. Multiply the rounded numbers: Multiply the rounded numbers to get an estimated product.
  3. Check the estimate: Check if the estimated product is close to the actual product.

Estimating the Factors of the Given Expressions

Now, let's apply the steps above to estimate the factors of the given expressions.

Expression A: (29.5)(1.7)

  • Round the numbers: 29.5 ≈ 30, 1.7 ≈ 2
  • Multiply the rounded numbers: 30 × 2 = 60
  • Check the estimate: The estimated product is close to the actual product.

Expression B: (13.2)(4.5)

  • Round the numbers: 13.2 ≈ 13, 4.5 ≈ 5
  • Multiply the rounded numbers: 13 × 5 = 65
  • Check the estimate: The estimated product is not close to the actual product.

Expression C: (4.67)(9.8)

  • Round the numbers: 4.67 ≈ 5, 9.8 ≈ 10
  • Multiply the rounded numbers: 5 × 10 = 50
  • Check the estimate: The estimated product is not close to the actual product.

Expression D: (7.3)(8.52)

  • Round the numbers: 7.3 ≈ 7, 8.52 ≈ 9
  • Multiply the rounded numbers: 7 × 9 = 63
  • Check the estimate: The estimated product is not close to the actual product.

Based on the estimates, we can conclude that Expression A: (29.5)(1.7) has an estimated product of 60. This is because the estimated product of 30 × 2 is close to the actual product.

Here are some tips and tricks to help you estimate factors:

  • Round numbers: Round numbers to the nearest whole number or to one decimal place.
  • Multiply rounded numbers: Multiply the rounded numbers to get an estimated product.
  • Check the estimate: Check if the estimated product is close to the actual product.
  • Use mental math: Use mental math to estimate the factors of an expression.
  • Practice: Practice estimating factors to improve your skills.

Estimating factors is an essential skill in mathematics that helps us approximate the value of a quantity or expression. By following the steps outlined in this article, you can estimate the factors of an expression and solve for the product. Remember to round numbers, multiply the rounded numbers, and check the estimate. With practice, you can become proficient in estimating factors and solve problems quickly and accurately.
