A class, two students Meenakshi and Devna were very good friends. While doing combined study, they found that all the rational numbers are either terminating or non-terminating recurring decimal expansion. They also found that the denominators of rational numbers having terminating decimal expansions are in theform Based on this answer the following.The Prime factors of the denominator of is(b)8. The decimal expansion of will(c)(a) Terminate (b) Recurring (c) Non terminate9. If the denominator of is of the form, then the value of n is(a) 1(b) 2 2(c) 310. If the decimal expansion of will terminate, then after how many places of decimals.(a) 2(b) 311. The decimal representation of is(a) 0.85(b) 0.805. s 12. Find the HCF (865, 255) using Euclid's division lemma(c) 0,085(3)+1 (3) 13. Show that the square of any positive integer is of the form 3m or3m+114. Prove that is irrational.(4)
