Question

11 use compatible numbers to estimate the missing factor. 532 × □ = 158,536 the missing factor is approximately ?

Explanation:

Step1: Rewrite to find missing factor

To find the missing factor, rearrange the equation to divide the product by the known factor:
$$\text{Missing factor} = \frac{158,536}{532}$$

Step2: Use compatible numbers

Round 532 to 500 and 158,536 to 150,000 (compatible for easy division):
$$\frac{150,000}{500} = 300$$

Step3: Verify with closer estimates

For a better estimate, round 532 to 530 and 158,536 to 159,000:
$$\frac{159,000}{530} = 300$$

Answer:

300
