1/2= ?/8+3/?=?/12
find the missing number to make these fractions equal.

  (1, 8, 6) or (2, 12, 6) or (3, 24, 6)

Step-by-step explanation:

The last number must be 6:

  1/2 = 6/12

The other two numbers cannot be 6, but can have several values:

  1/2 = 1/8 +3/8 = 6/12

  1/2 = 2/8 +3/12 = 6/12

  1/2 = 3/8 +3/24 = 6/12

__

There are a variety of negative solutions as well. For example, ...

  1/2 = -8/8 +3/2 = 6/12

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
