Q.1 Convert the given fractional numbers to percent.
(a) \(\frac{1}{8} \)
(b) \(\frac{5}{4} \)
(c) \(\frac{3}{40} \)
(d) \(\frac{2}{7} \)


Answer :

(a) \(\frac{1}{8} \)= \(\frac{1×100}{8×100} \)=\(\frac{100}{8} \)%=\(12\frac{1}{2} \)%
(b) \(\frac{5}{4} \)= \(\frac{5×100}{4×100} \)=\(\frac{5×100}{4} \)%=125%
(c) \(\frac{3}{40} \)= \(\frac{3×100}{40×100} \)=\(\frac{3×100}{40} \)%=\(\frac{15}{2}% \)=\(7\frac{1}{2} \) %
(d) \(\frac{2}{7} \)= \(\frac{2×100}{7×100} \)=\(\frac{200}{7} \)%=\(28\frac{4}{7} \)%
