Consider three fractions: 17/8, 64/455 and 15/1600. Without long division, classify how many of these are terminating decimals. (Factorise each denominator.)

Question

Accepted Answer

2. 8 = 2^3 (terminating); 455 = 5 × 7 × 13 (recurring); 1600 = 2^6 × 5^2 (terminating). So 2 of the 3 are terminating.
