Answer 1

1)558,720:20:9*5-6,140:20=15,52-0,307=15,273
2)5,680:8*7-6,140:20=4,97-0,307=4,663

Answer 2

Let's solve the given mathematical expression step by step:

1. 558.720 ÷ 20 = 27.936
2. 27.936 ÷ 9 = 3.104
3. 3.104 × 5 = 15.520
4. 6.140 ÷ 20 = 0.307
5. Now subtract 0.307 from 15.520: 15.520 - 0.307 = 15.213

Next part of the expression:

1. 5.680 ÷ 8 = 0.710
2. 0.710 × 7 = 4.970
3. Now subtract 6.140 ÷ 20 from 4.970: 4.970 - 0.307 = 4.663

So, the two expressions are:

1. 558.720 ÷ 20 ÷ 9 × 5 - 6.140 ÷ 20 = 4.663
