To add fractions, you find the least common multiple.
But, a faster way would be multiply the two denominators together:

x/20 + /20 
How many times does 4 go into 20? 5 times. 5 times 1 equals 5.
5/20 + x/20
How many times does 5 go into 20 4 times? 4 times 1 equals 4.

5/20 + 4/20 = 9/20. This is the final answer because it can't be simplified any more.

An editor has a stack of k documents to review. The order in which the documents are reviewed is random with each ordering being
ladessa [460]

Using the probability concept, it is found that there is a \mathbf{\frac{1}{k}} probability that “Relaxation Through Mathematics” is first to review.

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

  • There is a total of k documents to be reviewed, hence T = k.
  • Of those documents, 1 is named “Relaxation Through Mathematics”, hence D = 1

The <em>probability </em>is:

p = \frac{D}{T} = \frac{1}{k}

  d = √(12² +5²) = √(144 +25) = √169 = 13 . . . cm

The width of the divider is 13 cm.

The height of the divider is shown as 12 cm.

The dimensions of the dividing rectangle are 13 cm by 12 cm.
