Q1 (10)   Without actually performing the long division, state whether the following rational
numbers will have a terminating decimal expansion or a non-terminating repeating decimal
expansion:  77 / 210

$\\\frac{77}{210}=\frac{7\times 11}{2\times 3\times5\times 7 }\\ \frac{77}{210}=\frac{11}{2\times 3\times5}$
