Question 48556
Adding Fractions
Remember: the denominators must be the same
Ex.) {{{1/2 + 1 = 1/2 + 2/2 = (1 + 2)/2 = 3/2}}}
Ex.) {{{3/4 + 5/6 = 9/12 + 10/12 = (9 + 10)/12 = 19/12}}}
Subtracting Fractions
Remember: the denominators must be the same
Ex.) {{{1 - 1/2 = 2/2 - 1/2 = (2 - 1)/2 = 1/2}}}
Ex.) {{{6/7 - 7/21 = 18/21 - 7/21 = (18 - 7)/21 = 11/21}}}
Multiplying Fractions
Remember: multiply the numerator by the numerator and multiply the denominator by the denominator
Ex.) {{{(3/2)(1/4) = (3*1)/(2*4) = 3/8}}}
Ex.) {{{(2/11)(10/2) = (10*2)/(2*11) = 10/11}}}
