Answer 1

Răspuns:

Explicație pas cu pas:

(8x45 + 11) / 45 - (7x30+1)/30 = 371 / 45 -211 / 30 = (371x2 - 211x3)/90 =

= (742-633)/90 = 109/90

(5x25+11)/25 - (4x5+3)/5 = 136/25 - 23/5 = (136 - 23x5)/25 = 136-115 / 25 = =21/25

(9x24+17)/24 - (8x4+3)/ 4 = 233/24 - 27/4 = (233 - 27x6)/24 = 233-162/24=

= 71/24
