in this question, given that we need a specified number of cups to make some cookies, given another number of cookies, we are to find the number the number of cups necessary to make it.
From the question;
1 1/4 sugar cups makes 20 cookies
x sugar cups will make 14 cookies
Hence;
1 1/4 * 14 = x * 20
Kindly note that 1 1/4 is same as 5/4;
Thus;
5/4 * 14 = x * 20
70/4 = 20x
Divide both sides by 20
70/(20 * 4) = x
70/80 = x
x = 7/8
7/8 cups of sugar is needed to make 14 cookies
