Question

(-1/12+2/5)-(-0-,37-0,63)-1целых 13/15 по действиям пжж​

Answer 1

Ответ:

(-5/60+24/60)-(-1)-1 13/15=

=19/60+1-1 13/15=1 19/60-1 52/60=-33/60=-11/20

Answer 2

To simplify this expression, we can follow the order of operations (PEMDAS) and simplify each operation one by one:

1. Simplify (-1/12 + 2/5):

   First, we need to find a common denominator, which is 60. We can convert -1/12 to -5/60 and 2/5 to 24/60.

   (-5/60 + 24/60) = 19/60

   So (-1/12 + 2/5) = 19/60

2. Simplify (-0.37 - 0.63):

   (-0.37 - 0.63) = -1

3. Simplify 1 целых 13/15:

   1 целых means 1 whole number, which is 1, and 13/15 is the fraction part.

   So 1 целых 13/15 = 1 + 13/15 = 28/15

Now we can substitute these simplified values into the original expression:

(19/60) - (-1) - (28/15)

To subtract -1, we can change it to +1 and change the sign of the other terms inside the parentheses:

(19/60) + 1 + (28/15)

We can find a common denominator of 60:

(19/60) + (60/60) + (112/60)

Combine the numerators:

191/60

So the final answer is 191/60.
