Question

If three smiles equals 10 grins, and 6 grins equals 9 laughes, how many laughes does it take to equal 2 smiles

Answer 1

if 3 smiles=10grins
then,1smile=10/3=3.33

and 6 grins =9 laughes
then,1grin=9/6=1.5

therefore,2 smiles=6.66 grins
and6.66 grins=6.66*1.5=9.99 or approax 10 laughs

therefore 10 laughs take to equal 2 smiles..
