А) 21,46 : 5,8 + 24,94 : 5,8; Б) 20,64 : 4,3 + 22,36 : 4,3;В) 6,7 * (35,712 : 4,8 + 3,36):Г) 3,8 * (8,57 + 9,585 : 4,5);Д) (2,6 * 1,34 - 2,269) : 4,5;Е) (2,3 * 1,18 - 1,419) : 3,7.

Answer 1

А) 21,46 : 5,8 + 24,94 : 5,8=3,7+4,3=8

Б) 20,64 : 4,3 + 22,36 : 4,3=4,8+5,2=10

В) 6,7 * (35,712 : 4,8 + 3,36)=6,7 * (7,44+3,36)=6,7 * 10,8=72,36

Г) 3,8 * (8,57 + 9,585 : 4,5)=3,8 * (8,57+2,13)= 3,8 * 10,7=40,66

Д) (2,6 * 1,34 - 2,269) : 4,5=(3,484-2,269):4,5=1,215:4,5=0,27

Е) (2,3 * 1,18 - 1,419) : 3,7=(2,714-1,419):3,7=1,295:3,7=0,35

Answer 3

Let's solve each expression step by step:

А) 21.46 / 5.8 + 24.94 / 5.8: First, divide 21.46 by 5.8: 3.7017241379310345 Then, divide 24.94 by 5.8: 4.3017241379310345 Finally, add the results: 3.7017241379310345 + 4.3017241379310345 = 8.003448275862069

Б) 20.64 / 4.3 + 22.36 / 4.3: First, divide 20.64 by 4.3: 4.8 Then, divide 22.36 by 4.3: 5.2 Finally, add the results: 4.8 + 5.2 = 10

В) 6.7 * (35.712 / 4.8 + 3.36): First, divide 35.712 by 4.8: 7.440 Then, add 7.440 and 3.36: 10.800 Finally, multiply 6.7 by 10.800: 72.36

Г) 3.8 * (8.57 + 9.585 / 4.5): First, divide 9.585 by 4.5: 2.13 Then, add 8.57 and 2.13: 10.70 Finally, multiply 3.8 by 10.70: 40.66

Д) (2.6 * 1.34 - 2.269) / 4.5: First, multiply 2.6 by 1.34: 3.484 Then, subtract 2.269 from 3.484: 1.215 Finally, divide 1.215 by 4.5: 0.27

Е) (2.3 * 1.18 - 1.419) / 3.7: First, multiply 2.3 by 1.18: 2.714 Then, subtract 1.419 from 2.714: 1.295 Finally, divide 1.295 by 3.7: 0.35

So, the results are: А) 8.003448275862069 Б) 10 В) 72.36 Г) 40.66 Д) 0.27 Е) 0.35
