Any REMAINDER, which appears after the operation of division, is the numerator of a fraction, the divisor being the denominator; and this fraction forms a part of the quotient. Therefore, place the remainder and the divisor, as a fraction, to the right of the quotient. 2.

The sum of these fractions will be an improper fraction, and it must be changed to a mixed number. 2. What is the sum of 491 ii, 75 i and 336 61? 491 11 In this example, we add together 75 4 the elevenths, and find their sum to 11 be 11; which is equal to 21. The we write down, and carry the 2 to 140411 the column of units. 3. What is the sum of 419, 184, 124, 85734, 9, 251 %, 141, and 254 ? 4.

We then proceed 3817 to take 6 units from 7 units. 8366 A 6. Subtract 460314 from 71706. 8. If 175 yards of cloth be cut from a piece contain ing 49 yards, how much will be left? 9.

What is the product of 864, multiplied by 9? 86 We multiply by 9 thus, 9 times $ 9 is 30 ; equal to 57. Then we write this under the 4, and carry the 5 to 7797 the product of the 6 units. 2. What is the product of 41,, multiplied by 7? 3. What is the value of a field, which contains 5 acres, allowing it to be worth 54 dollars per acre ? 4. How much is 4 times 3517? 54 Here we are obliged to multiply by 28 8 units and 2 tens separately, and we 432 cannot well bring in the product of the 108 fraction by the 2 tens. Therefore, 18 we first multiply the whole numbers, and then find 28 times š, in a separate 15303 operation, which is not here written. 7. How much is 92 times 20514? 8.
