3 per 5+1 per 2=n-1 per 4nilai n adalah?

Jawab:

$frac{3}{5} + frac{1}{2} = frac{(n-1)}{4} \\frac{6+5}{10} =frac{(n-1)}{4} \\frac{11}{10} =frac{(n-1)}{4} \\11 times 4 =10 times (n-1)\\44 =10n -10\\44+10 =10n\\54 = 10n\\n = frac{54}{10} \\n = 5,4$

Semoga bermanfaat

Jawaban:

n = 27/20

Penjelasan dengan langkah-langkah:

3/5 + 1/2. = n – 1/4

n = 3/5 + 1/2 + 1/4 = 12/20 + 10/20 + 5/20 = 27/20

n = 27/20

PEMBUKTIAN

3/5 + 1/2 = 27/20 – 1/4

12/20 + 10/20 = 27/20 – 5/20

22/20. = 22/20
