FTCE Math Exam with Correct Solutions
6(5 + 3) = (6 x 5) + (6 x 3) exemplifies - The distributive property of multiplication over addition. PEMDAS is an acronym for remembering - the order of operations. 3+addend = sum - 3+addend = sum Minuend - Subtrahend = Difference - Minuend - Subtrahend = Difference 3 x Factor = Product - 3 x Factor = Product Divided / Divisor = Quotient - Divided / Divisor = Quotient Multiplicative property - ax1=a Property of reciprocals - a x 1/a = a Additive property of 0 is - a + 0 = a Commutative property for addition/multiplication is - a+b = b+a A x b = b x a Associative property for addition/multiplication - Associating or grouping three or more addends or factors in a different way does not change the sum or product - (3 + 7) + 5 = 3 + (7 + 5) Distributive Property of Multiplication over addition - a(b+c) = (axb) + (axc) Convert fraction to a decimal - Divide numerator by denominator (1 divided by 4 = .25, 4 goes into 1 .25 times) Convert non-repeating (terminating) decimal to a fraction - Write decimal as a fraction with the denominator a power of 10 and then reduce to lowest terms (0.125 can be written as 125/1000 which reduces to 1/8) Convert decimal to percent - Shift decimal 2 places to the right and add the percent symbol (.145 = 14.5%)
