Question

If someone drank 3 fourthes of a 16 ounce bottle . how many ounces are left

Answer 1

how many fourths are there in 16 wholes?


`\bf 16\implies \cfrac{16}{1}\implies \cfrac{16\cdot 4}{1\cdot 4}\implies \stackrel{\textit{fourths in 16 wholes}}{\cfrac{64}{4}} \\\\\\ \textit{now someone takes away }(3)/(4)\textit{ from that}\qquad \cfrac{64}{4}-\cfrac{3}{4} \\\\\\ \cfrac{64-3}{4}\implies \stackrel{leftover}{\cfrac{61}{4}}`

Answer 2

look at the demoninator, 1/4 of 16 is 4 ,you have 3 fourths so multiply 4 by 3 and you get 12 16-12 and the answer is 4
