4,2 × [ -6/7] + 5 1/8 =#pake cara# no ASAL!!!

Penjelasan dengan langkah-langkah:

$tt4.2 times ( - frac{6}{7} ) + 5 frac{1}{8} =$

$= - frac{18}{5} + frac{41}{8}$

$= frac{ - 144}{40} + frac{205}{40}$

$= frac{( - 144 + 205)}{40}$

$= frac{61}{40}$

$bf = 1 frac{21}{40}$

$tt{ red{fr}}$

kesimpulan : 4,2 × ( -6/7) + 5 1/8 = 1 21/40.

Penjelasan dengan langkah-langkah:

= 4,2 × (-6/7) + 5 1/8

= 42/10 × (-6/7) + 41/8

= -252/70 + 41/8

= -2016/560 + 2870/560

= 854/560

= 1 294/560

= 1 21/40
