Basic Concepts on Fraction Fraction – is defined as a part of a whole. In some other books‚ it is defined as a number written in the form ab ‚ where “a” and “b” are numbers and “b” is not equal to zero. Basic Parts of a Fraction * Numerator – the number above tells how many parts are taken. * Denominator – the number below tells how many equal parts the whole is divided. * Fraction bar – line that separates the two numbers. It also indicates division. There are several kinds

Introduction: In this internal assessment‚ we will investigate a set of numbers that are presented in a symmetrical pattern. 5 rows of numbers are given in a shape of a triangle‚ therefore a connection can be made to Pascal’s triangle. Another hint can also easily be noticed as Lacsap is exactly the backwards of Pascal. The goal of the investigation is to find the general statement En(r)‚ where En(r) is the (r+1)th element in the nth row‚ starting with r=0. An example of this would be . In order

To solve a system of equations by addition or subtraction (or elimination)‚ you must eliminate one of the variables so that you could solve for one of the variables. First‚ in this equation‚ you must look for a way to eliminate a variable (line the equations up vertically and look to see if there are any numbers that are equal to each other). If there is lets say a –2y on the top equation and a –2y on the bottom equation you could subtract them and they would eliminate themselves by equaling zero

1.2 The original productivity of the line was 20 valves per hour. After the changes by John Goodale the line productivity was 22.5 valves per hour. The percent change was 12.5. We found the original productivity by dividing 160 valves produced by an 8-hour shift. The new line productivity was found by dividing 180 valves by an 8-hour shift. Calculating the difference between the new line productivity and the old-line productivity‚ and then dividing that number by the old-line productivity gave us
