To find the weight of the largest shirt size, we need to find the value that is 1 3/4 times as much as the smallest shirt size. To do this, we need to multiply the two numbers (14.5 x 1 3/4). In order to make this process easier, we can convert 1 3/4 into a decimal, which would be 1.75. After that, we just multiply; 14.5 x 1.75 = 25.375. Your answer is 25.375 ounces.
The ratio is 6w = 4f. Multiply both sides by 3/2 to get 6 cups of flour, and we have: 6*3/2 w = 4 * 3/2 f 18/2 w = 12/2 f 9 w = 6 f So 9 cups of water.
