Explanation Given information: The expression is 2000 − 327.47 _ . Use the below steps to subtract: Write the second number below the first number as the decimal places are lined up. Now, place the subtraction sign on the left of the second number. Now, subtract as whole numbers. 2000 − 327.47 _ Then, subtract the digits from the right to the left as whole numbers. Placing a zero to the right of the digits after the decimal in any number will not change any value. Now, insert the decimal and two zeros to the right of 0 in the first number so that the digits can be lined up neatly. 2000.00 − 327.47 _ Subtract the second place digits to the right of the decimal. Since 7 is larger than 0 , borrow 1 ten from the tens place. Since there is a 0 in the tens place, borrow 1 ones from the ones place. As there is another 0 in the ones place, borrow 1 ten from the tens place. There is yet another 0 in the tensplace, so borrow 1 hundred from the hundreds place. Since there is a 0 again in the hundreds place, borrow 1 thousand from the thousands place. 1 thousands=10 hundreds Split these 10 hundreds as 9 hundreds+10 tens . 1 hundred=10 tens Split these 10 tens as 9 tens + 10 ones . 1 tens=10 ones Split these 10 ones as 9 ones+10 tenths . 1 ones=10 tenths Split these 10 tenths as 9 tenths+10 hundredths . Thus, in the hundreds place, 0 becomes 0 + 10 = 10 ;in thetens place, 0 becomes 0 + 10 − 1 = 9 , the ones place digit 0 becomes 0 + 10 − 1 = 9 , the tens place 0 becomes 0 + 10 − 1 = 9 , thehundreds place digit 0 becomes 0 + 10 − 1 = 9 , and the thousands place 2 becomes 2 − 1 = 1 . 2 1 0 10 9 0 10 9 0 10 9 . 0 10 9 0 10 − 3 2 7 . 4 7 _ Subtract 7 from 10 , that is: 10 − 7 = 3 . 2 1 0 10 9 0 10 9 0 10 9 . 0 10 9 0 10 − 3 2 7 . 4 7 _ 3 Subtract the first place digits to the right of the decimal 4 from 9 , that is: 9 − 4 = 5 . 2 1 0 10 9 0 10 9 0 10 9 . 0 10 9 0 10 − 3 2 7 . 4 7 _ 5 3 Now, place the decimal as in the other numbers. 2 1 0 10 9 0 10 9 0 10 9 . 0 10 9 0 10 − 3 2 7 . 4 7 _ . 5 3 Subtract the number before the decimal 7 from 9 , that is: 9 − 7 = 2 . 2 1 0 10 9 0 10 9 0 10 9
