13/100 ÷ 11/20 =
first, you transform the ÷ to a ×, and you reverse the second fraction:
13/100 × 20/11=
then, you simplify 100 and 20 by dividing them by 10:
13/100÷10 x 20÷10/11 = 13/10 x 2/11
then, you multiply the numerators by each other, and the denominators by each others:
13×2/10×11 = 26/110
since 26 and 110 can be divided by 2, so you simplify them by dividing them by 2:
26÷2/110÷2 = 13/55
and that's the final answer: 13/55
Hope this Helps :D
