From experience, you do not always increse the ingredients proportinally or else you will get some srprise
but this rpblem assumes that
basically
since 2 and 1/3 increased to 7
we have to increase flour also
by how much?
2 and 1/3 times how many=7
7/3 times what=7
multpily both sides by 3/7 to clea fraction
what=21/7
what=3 times
so flour has to increase by 3 time aslso
2=orignal flour
2*3=6
flowur is now 6
B

solve for x
B is anser
