Divide 105 such that 1/3 of one part is equal to 1/4 of other part
a + b = 105 ... 3a + 3b = 315
a/3 = b/4 ... LCD is 12 ... 4a = 3b
substituting ... 7a = 315
solve for a , then substitute back to find b
a/3 = b/4 ... LCD is 12 ... 4a = 3b
substituting ... 7a = 315
solve for a , then substitute back to find b
