What is the difference between terminating and recurring decimals?
Terminating means it stops cleanly / has an end. Recurring means a digit pattern repeats endlessly.
Find the missing number to make this statement true: 2/3= _/12

Use the digits 1, 2, 4, and 8 exactly once each to create two fractions that are perfectly equal to each other.
1/2 = 4/8
1/4 = 2/8

Without converting them into division problems, explain why 3/8 will terminate but 2/3 will recur.
The prime factors of the denominator 8 are only 2s 2 \times 2 \times 2\) , which guarantees it terminates. The denominator 3 contains a prime factor other than 2 or 5, meaning it must recur.
Using the digits 1, 2, 3, 4, 5, 6, 7, 8, and 9 exactly once each, complete these three equivalent fractions:
2/6 = _/9 = 18/_ _
The missing numbers are 3 and 54 (to form
\(\frac{2}{6} = \frac{3}{9} = \frac{18}{54}\)
