Question

(85-68)*(56:14) 68:2+16*4 94:5-38:2 420:6*5+639 520-(190-100:4) 4800:60*20+(28397-9148)

Answer 1

(85 - 68) * (56 : 14) =17 * 4 = 68
68:2+16*4 = 34 + 64 = 98
(может там 95?) 95:5-38:2= 19-19 =0
420:6*5+639=70*5+639=350+639=989
520-(190-100:4)= 520-(190-25)=520-165=355
4800:60*20+(28397-9148)=80*20+19249=1600+19249=20849

Answer 3

Let's solve each expression step by step:

1. (85-68)(56:14) = (17)(56/14) = (17)*(4) = 68

2. 68:2+164 = 34 + 164 = 34 + 64 = 98

3. 94:5-38:2 = 18.8 - 19 = -0.2

4. 420:65+639 = 705 + 639 = 350 + 639 = 989

5. 520-(190-100:4) = 520 - (190 - 25) = 520 - 165 = 355

6. 4800:6020+(28397-9148) = 8020 + 19249 = 1600 + 19249 = 20849

So, the results of the expressions are:

1. (85-68)*(56:14) = 68
2. 68:2+16*4 = 98
3. 94:5-38:2 = -0.2
4. 420:6*5+639 = 989
5. 520-(190-100:4) = 355
6. 4800:60*20+(28397-9148) = 20849
