Penjelasan dengan langkah-langkah:

1 . $frac{2}{3}$ + $frac{3}{4\}$ – $frac{1}{6}$ = sama kan yg dibawah

= $frac{8}{12}$ + $frac{9}{12}$ – $frac{2}{12}$

= $frac{17}{12}$ – $frac{2}{12}$

= $frac{15}{12} = 1frac{3}{12} = 1 frac{1}{4}$

2. 9/10 – 2/5 + 3/4

= 18/20 – 8/20 + 15/20

= 10/20 + 15/20

= 25/20

= 1 5/20 = 1 1/4

3 . 1 3/5 + 2 1/6 – 1/2

= 8/5 + 13/6 – 1/2

= 48/30 + 65/30 – 15/30

= 98/30

= 3 8/30 = 3 4/15

4 . ( 2 + 4 ) + ( 2/3 + 3/5 – 4/15)

= 6 + (10/15 + 9/15 – 4/15 )

= 6 + 15/15

= 7
