Algebra.Com's Answer #141592 by ilana(307)![]() ![]() ![]() You can put this solution on YOUR website! I would think of this like regular subtraction. Suppose you wanted to find 543 - 365. You would start with ones. You can't do 3-5, so you borrow ten from the tens column. So you have 13-5, which is 8 ones. Now you look at tens. You borrowed one ten, so you are left with 3-6. You can't do that, so you borrow one from the hundreds column. So you have 13-6, or 7. Now you look at hundreds. You borrowed one hundred, so you are left with 4-3, or 1. So the answer is 1 hundred, 7 tens, and 8 ones, or 178. \n" ); document.write( "1) You can't subtract 12in from 10in, so you borrow 1 foot. Since 1ft is 12 inches, you now have 22in-12in, or 10in. Now look at ft. You can't do 13ft-17ft, so borrow a yard. Since 1yd is 3ft, you now have 16ft-17ft, which you still can't do. So borrow another yd. So you have 19ft-17ft, or 2 ft. Now look at yds. You borrowed 2yd, so you have 24 left. 24yd-13yd = 11yd. So the answer is 11yd, 2ft, 10in. \n" ); document.write( "Another way to complete these is to convert everything to the smallest unit, in this case inches, and then subtract. So you would have (936+168+10)in - (468+204+12)in = (1114-684)in = 430in. But then you probably need to convert that back to yds, ft, and inches, which is why I like the borrowing method better. Best of luck! \n" ); document.write( " |
