equal.
,ATI TEARS Nursing exam with questions and answers (100% solved)
2) Subtraction axiom
If you subtract the same number of expressions from each side of an equation, the equation
remains equal.
3) Multiplication axiom
If you multiply by each side of an equation by the same number or expression, the equation
remains equal.
4) Division axiom
If each side of an equation is divided by the same number or expression, the equation remains
equal. - ✔✔✔-What are the four axioms of algebra?
1) Drop the % symbol 20% to 20
2) Divide the number by 100 20 ÷ 100 = 1/5
3) Reduce the fraction to its lowest terms.
4) Change the mixed number is necessary. - ✔✔✔-How do you change a percent (%) into a
fraction?
1) Drop the % symbol. When you drop the % symbol from a whole number, a decimal point
takes the place of the symbol. For example, when you drop the % symbol from 68.1%, the
decimal point replaces the % symbol.
2) Divide by 100 by moving the decimal point two places to the left. 68.1 = 0.681
3) Add zeroes as needed. - ✔✔✔-How do you change a percent (%) into a decimal?
1) Multiply by 100 by moving the decimal point two places to he right. For 3.19 you would move
the decimal point two places to the right, so 3.190 = 319.0
2) Add zeroes as needed.
3) Add the % symbo. 319.0 = 319% - ✔✔✔-How do you change a decimal to a percent (%) ?
1) Multiply the fraction by 100. 1/2 X 100/1 = 100/2
, ATI TEARS Nursing exam with questions and answers (100% solved)
2) Reduce if necessary. 100/2 = 50/1 = 50
3) Change the improper fraction to a mixed number.
4) Add the % symbol. - ✔✔✔-How do you change a fraction into percent (%)?
1) Perform any multiplication or division before performing addition or subtraction.
2) The order in which you multiply numbers and letters in a term does not matter.
3) The order in which you add terms does not matter.
4) If there are roots or powers in any term, you may be able to add or simplify the term by using
the laws of exponents.
5) Combine like (similar) terms. Like terms are terms which have exactly the same letters raised
to the same powers. - ✔✔✔-What are the rules for simplifying expression into a simpler one?
1) Write down what is available or known in a fraction format.
2) Complete the proportion by writing down what you desire in a fraction format, making sure
that the numerators and the denominators are like units.
3) Cross multiply the numerator of each ratio by its opposite denominator.
4) Solve for X using division. - ✔✔✔-How do you solve for x?
