Algebra.Com's Answer #74188 by doukungfoo(195)![]() ![]() You can put this solution on YOUR website! Ok, first we are told that: \n" ); document.write( "On a road map with a scale of 1/4 inch per 10 miles \n" ); document.write( "So this means that when measuring distance on the map every 1/4 ince is equal to 10 miles in the real world. \n" ); document.write( "Next we are told: \n" ); document.write( "the highway from Waukee to Winterset is 1 3/8 inches long \n" ); document.write( "And we are asked: \n" ); document.write( "How many miles long is this highway?\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Ok so the first thing we have to do is figure out how my 1/4 inch sections are in 1 3/8 inches. \n" ); document.write( "Well before I do anything towards solving the problem I am going to go ahead and change these fractions to decimal form. 1/4 = .25 \n" ); document.write( "and 1 3/8 = 1.375 \n" ); document.write( "Ok now how many times will .25 divide into 1.375 \n" ); document.write( "1.375/.25 = 5.5 \n" ); document.write( "So there are 5.5 one quarter inch sections in 1.375 \n" ); document.write( "Each one of these 5.5 is equal to 10 miles so..... \n" ); document.write( "5.5 * 10 = 55 \n" ); document.write( "So the answer is 55 miles \n" ); document.write( " |
