... the numerator and denominator by the same common factor. Ex: With 10/12 you can divide the numerator and denominator by 2 to get 5/6. You can find equivalent fractions with common denominators for adding or subtracting by multiplying the numerator and denominator by the same number. Ex: With 2/8 + ...

... A number system consists of an ordered set of symbols (digits) with relations defined for addition, subtract, multiplication, and division. The radix of a number system is the total number of digits allowed in the system. Any number in a system can have both an integer (whole) part and a fractional ...

Math Review
... try the multiplication or division first. » (A - D) / (C + F) = B » to solve for C, first rearrange the equation to it will read C=? Do this by multiplying both sides by C + F (since it is on the bottom of a fraction (denominator). » (A - D) * (C + F) / (C + F) = B * (C + F) » (A - D) = B * (C + F) ...
