Answer 1

Ответ:

Пошаговое объяснение:

(-1/12+2/5)-(-0,36-0,64)- 1 13/15=23/60

1) - 1/12+ 2/5=(-5+2*12)/60=(-5+24)/60=19/60

2) -0,36-0,64=-1

3) 19/60 - (-1)= 19/60+1=1 19/60

4) 1 19/60 - 1 13/15=79/60 - 28/15=(79-28*4)/60=

(79-112)/60=-33/60=-11/20

Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Simplify each part of the expression. a) (-1/12 + 2/5) = Common denominator is 60, so:

-1/12 = -5/60 2/5 = 24/60

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

b) (-0.36 - 0.64) = -1.00

c) 1 13/15 = To convert mixed fraction to an improper fraction, multiply the whole number (1) by the denominator (15) and add the numerator (13):

1 * 15 = 15 15 + 13 = 28

The improper fraction is 28/15.

Step 2: Now, let's put everything together:

(19/60) - (-1.00) - (28/15)

Step 3: To subtract a negative number, we change it to addition:

(19/60) + 1.00 - (28/15)

Step 4: Find the common denominator between 60 and 15, which is 60:

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

Step 5: Add the fractions:

[(19 + 60)/60] - (112/60)

Step 6: Continue simplification:

(79/60) - (112/60)

Step 7: Now, we can subtract the fractions:

(79 - 112)/60

Step 8: Simplify the numerator:

-33/60

Step 9: Reduce the fraction to its simplest form:

-11/20

So, the final result of the expression is -11/20.
