4 3/5 + 6/8 – 4 1/4 = … pakai jalan nya ya kk thank you

Jawab:

$1frac{1}{10}$

Penjelasan dengan langkah-langkah:

$4 frac{3}{5} + frac{6}{8} - 4frac{1}{4} =$

$(frac{23}{5} + frac{6}{8}) - 4 frac{1}{4} =$

$frac{184}{40} + frac{30}{40} = frac{214}{40}$

$frac{214(:2)}{40(:2} = frac{107}{20}$

$frac{107}{20} - 4 frac{1}{4} =$

$frac{107}{20} - frac{17}{4} =$

$frac{428}{80} - frac{340}{80} = frac{88}{80}$

$frac{88(:8)}{80(:8)} = frac{11}{10}$

$frac{11}{10}= 1 frac{1}{10}$

Jawaban:

4 3/5 + 6/8 – 4 1/4

23/5 + 3/4 – 17/4

92/20 + 15/20 – 85/20

(92+15)/20 – 85/20

(107-85)/20

22/20

1 2/20

= 1 1/10
