@ 5 + 2 to add these fractions, we first determine L.com of 12 & 8, 100 and hom of 12 48 is 24. Divide 24 by 12 & then multiply bys we get I again Divide 29 by 8 & then multiply by 3 we get 3x3=9 . then adding 10 e 9 we get 10 Finally we get a fraction to as numerator f 29 as denominator le. 3. 2757373 + 38 = - 10+0 19 2 = 24 - 24 4x lomaf 943) + 25 (mod sez) 23+27 lemof 923 ® - 4 x 3 + 2 + 3 4+ 6 10 4 + 6 Ba Denominatons of hoe 38 ase - 20 and 28 then the beast common denominators of 7 and 3 is the lom of 20 and 28 therefore the beast Common denominator of I and 2 is 140. ② two othersom denominators of 27 16 and 2 Common are 2x190=280 and 3 140= 420
