58/7 as a mixed number would be 8 2/7.
I do nothing really complicated.
7 times what equals 58? Or is close to 58? It would be 8. 7 x 8 = 56
How far is 56 from 58? By two numbers.
So, the mixed number would have 8 wholes, and 2/7 of a whole.
8 2/7.
It was a little hard for me to explain it, but hope this helps! :)
