SECTION VI—DIVISION BY FRACTIONS
73

The total is 14 141561971194138816791776, which multiplied by 1231217 makes 33.

Problem 32
A quantity, its 13, and its 14, added together, become 2. What is the quantity?

Multiply 11314 so as to get 2.

  1 11314
\ 23 1118
\ 13 12136
\ 16 14172
\ 112 181144

Take 12 times 12.

  1 12
  2 24
\ 4 48
\ 8 96
Total 144.

We will apply our fractions to 144. For the given expression we have

\ 1 144
\ 13 48
\ 14 36
Total 228.

The products above, taken as parts of 144, are equal to
228152763819.

The sum of the numbers here that correspond to the multipliers checked is equal to 285 and requires 3 more to make up 288, or 2 times 144. As 11314 times 144 is 228 we shall have as a continuation of our first multiplication,

\ 1228 1144 or 1 as a part of 144
\ 1114 172 " 2 " " " " 14

Adding together all the multipliers checked in this multiplication, we have 11611211141228 as the required quantity.


    the former multiplication are the multipliers of the latter and so are represented in the left-hand column here, while the multipliers of the former are the alternative numbers, 1, 2, 12, and 14, given at the right.
