3. $frac{1}{4} + frac{2}{4} = frac{1 + 2}{4} = frac{3}{4} = 0.75$

4. $frac{2}{3} + frac{1}{2} = frac{2 times 2 + 3 times 1}{3 times 2} = frac{4 + 3}{6} = frac{7}{6} = 1 frac{1}{6} = 1.16666666667$

5. $frac{1}{5} + frac{2}{3} = frac{1 times 3 + 5 times 2}{5 times 3} = frac{3 + 10}{15} = 0.86666666666$

6. $frac{2}{5} + frac{3}{4} = frac{2 times 4 + 5 times 3}{5 times 4} = frac{8 + 15}{20} = frac{23}{20} = 1 frac{3}{20} = 1.15$

1/4 + 2/4

= 1+2/4

= 3/4

2/3 + 1/2

= 2x(2)/3x(2) + 1x(3)/2x(3)

(dikali supaya penyebutnya sama)

= 4/6 + 3/6

= 4+3/6

= 7/6 atau 1⅙

1/5 + 2/3

= 1x(3)/5x(3) + 2x(5)/3x(5)

(dikali supaya penyebutnya sama)

= 3/15 + 10/15

= 3+10/15

= 13/15

2/5 + 3/4

= 2x(4)/5x(4) + 3x(5)/4x(5)

= 8/20 + 15/20

= 8+15/20

= 23/20 atau 1 ³/20
