[tex] \tt = \frac{38}{5} - \frac{18}{10} \div \frac{14}{11 } \times \frac{68}{15} [/tex]
[tex] \tt = \frac{38}{5} - \frac{18 \times 11 \times 68}{10 \times 14 \times 15} [/tex]
[tex] \tt = \frac{38}{5} - \frac{13464}{2100} [/tex]
[tex] \tt = \frac{38 \times 420}{5 \times 420} - \frac{13464}{2100} [/tex]
[tex] \tt = \frac{15960}{2100} - \frac{13464}{2100} [/tex]
[tex] \tt = \frac{2496}{2100} = 1 \frac{33}{175} [/tex]
