Question

(4 1/3-(2/5)в кв.+3 1/75):4/75

Answer 1

(4 1/3 - 2/5² +3 1/75):4/75 = (13/3-2/5*2/5+226/75):4/75= (13/3-4/25+226/75):4/75= (325/75-12/75+226/75):4/75=539/75:4/75=539*75/75*4=539/4=134 3/4

Answer 2

(4 1/3 - (2/5)^2 + 3 1/75) : 4/75 = 134 3/4
1) (2/5)^2 = 4/25,
2) 4 1/3 - 4/25 + 3 1/75 = 13/3 - 4/25 + 226/75 = 325/75 - 12/75 + 226/75 = 539/75 = 7 14/75,
3) 7 14/75 : 4/75 = 539/75 * 75/4 = 539/4 = 134 3/4 (или 134,75)
