Question

$5 \times 2 \div 3 - 9 \div 4 \times 5 \div 8$
​

Answer 1

Oie, Td Bom?!

= 5 . 2 ÷ 3 - 9 ÷ 4 . 5 ÷ 8

= [5 . 2]/3 - 2,25 . 5 ÷ 8

= [5 . 2]/3 - 11,25 ÷ 8

= [5 . 2]/3 - 1,40625

= [5 . 2]/3 - 140625/100000

= [5 . 2]/3 - [140625 ÷ 3125]/[100000 ÷ 3125]

= 10/3 - 45/32 ⇐ MMC (3 . 32 = 96).

= 320/96 - 135/96

= [320 - 135]/96

= 185/96
