(2 6/7 + 1 3/5) x ( 5 1/3 - 2 1/2) =.......pakai cara ya

( 2 6/7 + 1 3/5 ) x ( 5 1/3 - 2 1/2 )
= (20/7 + 8/5) x (16/3 - 5/2)
= (100/35 + 56/35) x (32/6 - 15/6)
= 156/35 x 17/6
= 2.652/210
= 12 132/210
= 12 66/105
= 12 22/35

(2 6/7 + 1 3/5) x (5 1/3 - 2 1/2)
= (20/7 + 8/5) x (16/3 - 5/2)
= ((20 x 5 + 7 x 8)/(7 x 5)) x ((16 x 2 - 3 x 5)/(3 x 2))
= (156/35) x (17/6)
= 2.652/210
=  1.326/105
= 12 66/105
= 12 22/35
