Answer :

multiply both sides by 8
so  192 = 7 g
then divide both sides by 7
so  g = 192/7 = 27 3/7

but that does not seem to be one of your answers
24=7/8g
get rid of fractions
multiply both sides by 8
192=7g
divide both sides by 7
192/7=g
aprox
27 and 3/7
none of the answers are correct unless you typed 37 instead of 27
