1\ minue=(1)/(60)hour\\ 1(1)/(6)=(7)/(6)\\\\ (7)/(8)\ wall\ in\ (7)/(6)hours\\ x\ wall\ in\ (1)/(60)\\\\Proportion:\\ (7)/(8)\ - (7)/(6)\\ x-\ (1)/(60)\\\\cross\ multiplication\\\\ (7)/(8)*(1)/(60)=(7)/(6)x\\\\ (7)/(480)=(7)/(6)x\ \ \ | divide\ by\ (7)/(6)\\\\ (7)/(480)*(6)/(7)=x\\\\ x=(6)/(480)=(1)/(80)\\\\ In\ one\ minute\ Melinda\ will\ paint\ (1)/(80)\ of\ wall.
