<p>Assume that 1/4 quart of lemonade concentrate is mixed with 1 and 3/4 quarts of water to make lemonade for 4 people. How many quarts of lemonade concentrate are needed to make lemonade at the same strength for 14 people?</p>
<p>This too: On a report, the typing begins 3/4 inch from the left edge of the paper and ends 1 and 1/2 inches from the right edge. If the width of paper is 8 and 1/2 inches, how many inches per line is used for typing?</p>
<p>1/4 quart is needed for 4 people.</p>
<p>So, multiply the relationship by 3.5 to get the amount for 14 people, since 4*3.5=14</p>
<p>(1/4)*(7/2)=7/8=.875 quart of concentrate for 14 people.</p>
<p>For the paper one:</p>
<p>The total length is 8 and 1/2 inches. 3/4 on the left isn’t used, and 1 and 1/2 on the right isn’t used. So, the amount used for typing is (17/2)-((3/4)+(3/2))=25/4=6.25 inches used for typing.</p>
