Question

7 1/13* 4 15/17

Answer 1

If I understood: \[7\dfrac{1}{13}* 4\dfrac{15}{17}\rightarrow \mathrm{is\,\,the\,\,same\,\,of\,\,} \dfrac{92}{13}* \dfrac{83}{17}\] ... do you understand? Or not.

Answer 2

Because \[7 \dfrac{1}{13}=\dfrac{91}{13}+\dfrac{1}{13}\,\,and\,\,4 \dfrac{15}{17}=\dfrac{68}{17}+\dfrac{15}{17}\] ...ok?

Answer 3

Finally, \[\dfrac{92}{13}* \dfrac{83}{17}=\dfrac{92*83}{13*17}\,\,or\,\,\dfrac{7636}{221}\]
