Answer:
56/72 is repeating.
12/30 is terminating.
15/40 is terminating.
15/37 is repeating.
Explanation:
Terminating decimals have fractions which generally simplify into denominators of 2, 4, 5, 8, 10 etc. Repeating decimals have fractions which generally simplify into denominators of 3, 6, 7, 9, etc.
56/72 simplifies to 7/9. This is repeating.
12/30 simplifies to 2/5. This is terminating.
15/40 simplifies to 3/8. This is terminating.
15/37 does not simplify. This is repeating.
