Thank you very much sir! But we can also do this conversion without using a calculator. for example, in question 2, 𝝅/7*180/𝝅 =(180/7)° =(25 5/7)° [after finding the mixed fraction of 180/7] =25° (5/7*60)' [because 1°=60'] =25° (300/7) =25° (42 6/7)' [after finding mixed fraction of 300/7] =25°42' (6/7*60)" [because 1'=60"] =25°42'(360/7) =25°42'51" [approx.] Done! I hope this answer was helpful too, because the use of calculators is not allowed in class 11. Also, I think this method is easier than using the log book.... Thank you again.😀
Indian right?... Because only in countries like india calculators are not allowed till 12th grade .... Even i thought the same like "we can do it without calculator"😂😂
