⚠️Common Mistakes to Avoid

Dividing in the Wrong Order

Always divide the numerator by the denominator, not the other way around. For 71/80, divide 71 ÷ 80, not 80 ÷ 71.

Forgetting to Place the Decimal Point

When doing long division, make sure to place the decimal point correctly. A misplaced decimal can change your answer dramatically (0.08875 vs 0.8875).

Stopping Too Early with Repeating Decimals

While 71/80 terminates cleanly at 0.8875, some fractions produce repeating decimals. Always check if the pattern continues.

Confusing Fractions with Similar Numbers

Don't confuse 71/80 with similar fractions. Each fraction has a unique decimal value. For example, 71/80 = 0.8875, but changing either the numerator or denominator by even 1 gives a different result.

Understanding Terminating vs Repeating Decimals

✓ Terminating Decimals

A terminating decimal has a finite number of digits after the decimal point. It ends.

• Example: 1/4 = 0.25 (terminates after 2 digits)
• Example: 3/8 = 0.375 (terminates after 3 digits)
• Occurs when denominator factors are only 2s and 5s

71/80 = 0.8875 is a terminating decimal!

∞ Repeating Decimals

A repeating decimal has digits that repeat infinitely in a pattern.

• Example: 1/3 = 0.333... (3 repeats forever)
• Example: 2/7 = 0.285714... (pattern repeats)
• Occurs when denominator has factors other than 2 and 5
