1) (0,6739 + 1,4261) * 557,55 : (16,7 * 2,9 — 42,13);
2) (1,3892 + 0,8108) * 537,84 : (15,8 * 3,6 — 52,48);
3) 801,4 — (74 — 525,35 : 7,9) * (64,4 — 6,88 : 8,6);
4) 702,3 — (59 — 389,64 : 6,8) * (59,3 — 5,64 : 9,4).

1) $$\left(0{,}6739+1{,}4261\right)\cdot 557{,}55 : \left(16{,}7\cdot 2{,}9-42{,}13\right)$$

$$0{,}6739+1{,}4261=2{,}1$$

$$16{,}7\cdot 2{,}9=48{,}43$$

$$48{,}43-42{,}13=6{,}3$$

$$2{,}1\cdot 557{,}55=1170{,}855$$

$$1170{,}855:6{,}3=185{,}85$$

2) $$\left(1{,}3892+0{,}8108\right)\cdot 537{,}84 : \left(15{,}8\cdot 3{,}6-52{,}48\right)$$

$$1{,}3892+0{,}8108=2{,}2$$

$$15{,}8\cdot 3{,}6=56{,}88$$

$$56{,}88-52{,}48=4{,}4$$

$$2{,}2\cdot 537{,}84=1183{,}248$$

$$1183{,}248:4{,}4=268{,}92$$

3) $$801{,}4-\left(74-525{,}35:7{,}9\right)\cdot \left(64{,}4-6{,}88:8{,}6\right)$$

$$525{,}35:7{,}9=66{,}5$$

$$74-66{,}5=7{,}5$$

$$6{,}88:8{,}6=0{,}8$$

$$64{,}4-0{,}8=63{,}6$$

$$7{,}5\cdot 63{,}6=477$$

$$801{,}4-477=324{,}4$$

4) $$702{,}3-\left(59-389{,}64:6{,}8\right)\cdot \left(59{,}3-5{,}64:9{,}4\right)$$

$$389{,}64:6{,}8=57{,}3$$

$$59-57{,}3=1{,}7$$

$$5{,}64:9{,}4=0{,}6$$

$$59{,}3-0{,}6=58{,}7$$

$$1{,}7\cdot 58{,}7=99{,}79$$

$$702{,}3-99{,}79=602{,}51$$

Ответ

1) $$185{,}85$$; 2) $$268{,}92$$; 3) $$324{,}4$$; 4) $$602{,}51$$.
