Here are some tips for patterns and variables...
Study the number senteces at the right. All three sentences show the same general pattern.
+ This general pattern may be described in words: To find 10% of a number , mulitiply the number by 10\100 (or 0.10 , or 1/10)
The pattern may also be described be a number sentence that contains a varible : 10% of n = 10\100 * n .
A varible is a symbol, such as n, x ,A or a shape. A variable can stand for any one of many possible numeric values in a number sentences.
+ Number sentences like 10% of 50 = 10\100 * 50 and 10% of 200 are exsamples , or special cases , for the general pattern described by 10% of n = * n.
To write a special case for a gemeral pattern , replace the varible with a number
Exsample:
Geral pattern 10% of n = * n
Special case 10% of 35 = 10\100 * 35
