Question

20.14. Вычислите. 1) 16,52-(4,8 + 10,95)2) 4,8 - (0,98 + 1,75)3) (37,9 - 8,609) - (3,27 +0,9)4) 495,6- (10,9 + 275)5) (5,3 + 2,7) - (1,4 + 2,6)6) 76,309 + (7,251 - 5.6)​

Answer 1

1) 16,52-(4,8+10,95)=16,52-15,75=0,77

2)4,8-(0,98+1,75)=4,8-2,73=2,07

3)(37,9-8,609)-(3,27+0,9)= 29,291-4,17=25,121

4)495,6-(10,9+275)=495,6-285,9=209,9

5)(5,3+2,7)-(1,4+2,6)= 8-4 = 4

6)76,309+(7,251-5,6)=76,309+1,651=77,96

Answer 2

To compute the given expressions, follow these steps:

1. 16.52 - (4.8 + 10.95) = 16.52 - 15.75 = 0.77

2. 4.8 - (0.98 + 1.75) = 4.8 - 2.73 = 2.07

3. (37.9 - 8.609) - (3.27 + 0.9) = 29.291 - 4.17 = 25.121

4. 495.6 - (10.9 + 275) = 495.6 - 285.9 = 209.7

5. (5.3 + 2.7) - (1.4 + 2.6) = 8 - 4 = 4

6. 76.309 + (7.251 - 5.6) = 76.309 + 1.651 = 77.96

So the computed values are:

1. 0.77
2. 2.07
3. 25.121
4. 209.7
5. 4
6. 77.96
