Ответ:

4.5

Объяснение:

1)6.5*4.5=29.25

2) 5.2*1.36=7,072

3)29.25-7.072=22.178

4) 5/8*4.5=5/8*45/10=5/8*9/2=45/16

5)5/6*1.36=5/6*136/100=1/3*68/20=68/60=17/15

6)45/16-17/15=403/240

7) 5/13*22.178=8.53

8) 2.4*403/240=4.03

9) 8.53-4.03=4.5

Ответ:

4,5

Объяснение:

1) 6,5 * 4,5 = 29,25

2) 5 1/5 * 1,36 = 5,2 * 1,36 = 7,072

3) 29,25 - 7,072 = 22,178

4) 5/13 * 22,178 = 8,53

5) 5/8 * 4,5 = 5/8 * 45/10 = 45/16

6) 5/6 * 1,36 = 5/6 * 136/100 = 68/60 = 17/15

7) 45/16 - 17/15 = 675/240 - 272/240 = 403/240

8) 2,4 * 403/240 = 4,03

9) 8,53 - 4,03 = 4,5
