Answer 2

Answer:

We have to find the solution  

$1). \ 3\dfrac13 -1\dfrac14 = \dfrac {10}3 - \dfrac 54\\\\= \dfrac {40 - 15}{12}\\= \dfrac {25}{12}\\\\2).\ 5 \dfrac 12 - 3 \dfrac13 = \dfrac{11}2 -\dfrac {10}3 \\\\ = \dfrac{33- 20}6\\ = \dfrac {13}6\\\\ 3).\ 7\dfrac 18 - 6\dfrac 1 {10} = \dfrac{57}{8} -\dfrac {61}{10}\\\\= \dfrac {285 - 244}{40}\\= \dfrac {41}{40}\\\\4).\ 7\dfrac 12 - 3\dfrac 15\\= \dfrac {15}2 - \dfrac{16}5\\\\=\dfrac{75 - 32}{10}\\= \dfrac {43}{10}$
