2) (1,3892+0,8108)×537,84:(15,8×3,6-52,48)
Решите, плиз!

Answer 1

(0,6739+1,4261)×557,55÷(16,7×2,9-42,13)=185,85
0,6739+1,4261=2,1
16,7×2,9=48,43
48,43-42,13=6,3
2,1×557,55=1170,855
1170,855÷6,3=185,85

(1,3892+0,8108)×537,84÷(15,8×3,6-52,48)=268,92
1,3892+0,8108=2,2
15,8×3,6=56,88
56,88-52,48=4,4
2,2×537,84=1183,248
1183,248÷4,4=268,92
