no, 17-7=10 you still have the 1/10

OpenStudy (anonymous):

take away 1/10 from 10 you get 9 9/10

OpenStudy (anonymous):

10 2/20

OpenStudy (anonymous):

okay Jayda how did you get that im trying to undersand

OpenStudy (anonymous):

\[ {{7}{{1}\over{10}}}={{70+1}\over{10}}={{71}\over{10}}\]

OpenStudy (anonymous):

drop the 10 since its the only whole number then since the denominator of both fractions are 20 keep the twenty the same and just subtract 13 and 11.
