- 987/10,500
take LCM for 10,500
LCM=5×5×5×2×2×7×3
987/10,500=987/5×5×5×2×2×7×3
=329/5×5×5×2×2×7
=47/5×5×5×2×2
if a number has a denominator as 5 ^n and 2^m it is terminating
2.29/343
take lcm but I can say directly that this rational number will have non terminating decimal expansion
HOPE IT HELPS!!
