72,3 - 2,05 * (6,03 * 5,4 - 30,062=

Answer 1

(17,8+2,48) *5,05 - 13,85* 4,2=
20,28*5,05-58,17=
102,414-58,17=44,244


2,75+34,25 * (57,6 - 7,6 * 7,5)=
2,75+34,25*(57,6-57)=
2,75+34,25*0,6=
2,75+20,55=
23.30


72,3 - 2,05 * (6,03 * 5,4 - 30,062=
72,3-2,05*(32,562-30,062)=
72,3-2,05*2,5=
72,3-5,125=72,175
