“MATHEMATICS” Mathematics (from Greek μάθημα máthēma‚ "knowledge‚ study‚ learning") is the abstract study of topics encompassing quantity‚ structure space‚ change‚ and other properties; it has no generally accepted definition. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof. The research required to solve mathematical problems can take years or even centuries of sustained inquiry. Since the pioneering

the least orangey will be Mix A‚ mix a is in the tenths place but mix be is in the hundredths placed that’s why I said mix a is smaller because it has a smaller value. Also if you don’t know how to do it while dividing you can also chose fractions. For the fractions all you need to do is turn it into common denominators and solve. The part to whole ratio for Mix B is (6/14). Its 6/14 because the wanted to know how much concentrate to the total amount (juice.) All you need to do is put the
