a) 1/3+4/3 x (-1/2)=(-5/6) b) 5/3 x (-1/2)= (-5/6) c) __5x(-1)__ = __-5__ 3x2 6

d) =-5/6

3. Write a set of rules in your own words that describes how to convert:
 * decimals to fractions -
 * fractions to decimals - numerator divided by the denominator.
 * fractions to percents - numerator divided by the denominator times 100 gives you your answer. ex: 25/30x100= 83.3%.
 * percents to fractions - put the number from the percent over a 100 so it makes a fraction. ex: 25% = 25/100.
 * decimals to percents - multiply by 100.
 * percents to decimals-
