Answer 1

Ответ:

(12 2/3+0,7-12,7):0,05 = 37/60

1) 12 2/3 + 0,7= 12 2/3 + 7/10 = 12 20/30+21/30= 12 41/30 = 13 11/30

2) 13 11/30 - 12,7= 13 11/30 - 12 7/10 = 13 11/30 - 12 21/30 = 12 41/30 - 12 21/30= 20/30=2/3

3)2/3:0,05= 2/3: 5/100= 200/300:15/300=185/300= 37/60

Answer 2

Sure! I'll solve the expression for you step by step:

First, let's convert the mixed number 12 2/3 to an improper fraction: 12 2/3 = (12 * 3 + 2) / 3 = 38/3

Now, let's rewrite the expression with the updated fraction: (38/3 + 0.7 - 12.7) / 0.05

Next, let's perform the addition and subtraction inside the parentheses: 38/3 + 0.7 - 12.7 = 38/3 - 12 + 0.7 = (38 - 36 + 0.7) / 3 = 2.7 / 3 = 0.9

Now, we have: 0.9 / 0.05

Finally, let's perform the division: 0.9 / 0.05 = 18

Therefore, the result of the expression (12 2/3 + 0.7 - 12.7) / 0.05, solved step by step, is 18.
