People can be lefthanded, righthanded or ambidextrous. The number of boys in Canadian secondary schools who are left handed is about 1/7 the number of boys who are righthanded. About 11% of boys are lefthanded. Write and solve an equation to determine what percent of boys are righthanded.

1/7 RH= LH
.11B= LH
setting them equal
1/7 RH=.11B
RH/B= ????
