Answer:
31) They divided by 100, they're suppose to times 0.86 by 100 instead, which will be 86%
33) 0.34 x 100=34%
35) we do the inverse to turn it back into
a decimal which will be 0.36
[tex] \frac{36}{100} = \frac{18}{50} = \frac{9}{25} [/tex]
36) 16.24÷100=0.6424
[tex] \frac{16.24}{100} = \frac{8.12}{50} = \frac{4.6}{25} [/tex]
