Q.
⅝ × ⅔ + ⅛ = ?
12! + 6! – 5! = ?

Penjelasan dengan langkah-langkah:

frac{5}{8} times frac{2}{3} + frac{1}{8}

= frac{5}{4} times frac{1}{3} + frac{1}{8}

= frac{5}{12} + frac{1}{8}

= frac{5 times 2}{12 times 2} + frac{1 times 3}{8 times 3}

= frac{10}{24} + frac{3}{24}

bf = frac{13}{24}

12! + 6! – 5!

= (12.11.10.9.8.7.6.5.4.3.2.1) + (6.5.4.3.2.1) – (5.4.3.2.1)

= 479.001.600 + 720 – 120

= 479.001.600 + 600

= 479.002.200

5/8 × 2/3 + 1/8
= 5 × 2/8 × 3 + 1/8
= 10/24 + 1/8
= 10/24 + 3/24
= [ 13/24 ]
– – – – –
12! + 6! – 5!
= (1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10 × 11 × 12) + (1 × 2 × 3 × 4 × 5 × 6) – (1 × 2 × 3 × 4 × 5)
= 479.001.600 + 720 – 120
= 479.002.320 – 120
= [ 479.002.200 ]
