Respuesta :
firstly let's convert the mixed fractions to improper fractions and then divide.
[tex]\stackrel{mixed}{2\frac{2}{5}}\implies \cfrac{2\cdot 5+2}{5}\implies \stackrel{improper}{\cfrac{12}{5}} ~\hfill \stackrel{mixed}{2\frac{1}{10}}\implies \cfrac{2\cdot 10+1}{10}\implies \stackrel{improper}{\cfrac{21}{10}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{12}{5}\div \cfrac{21}{10}\implies \cfrac{12}{5}\cdot \cfrac{10}{21}\implies \cfrac{120}{105}\implies \cfrac{8}{7}\implies 1\frac{1}{7}[/tex]
Answer:
first make them improper fractions
2 2/5 = 12/5
2 1/10 = 21/10
now set them up
12/5 divided by 21/10
make 21/10 a reciprocal(flip the fraction upside down) and multiply across
12/5 x 10/21 = 1.14 or 1 1/7
