Пошаговое объяснение:

1-15/27=1-5\9=9-5\9=4\9

15-2 7/8=15-7\4=53\4

4-2/11=44-2\11=42\11

                                                                                                                                                                                                                                                                     

                             

Answer 3

It seems like you've provided three mathematical expressions. Let's solve each one step by step:

1. $1 - \frac{15}{27}$: To subtract fractions, you need a common denominator. In this case, the common denominator is 27.

$1 - \frac{15}{27} = \frac{27}{27} - \frac{15}{27} = \frac{27 - 15}{27} = \frac{12}{27}$

Now, you can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3.

$\frac{12}{27} = \frac{4}{9}$

2. $15 - \frac{2}{8}$: Simply subtract the whole number and the fraction:

$15 - \frac{2}{8} = 15 - \frac{1}{4} = \frac{60}{4} - \frac{1}{4} = \frac{60 - 1}{4} = \frac{59}{4}$

3. $4 - \frac{2}{11}$: Subtract the whole number and the fraction:

$4 - \frac{2}{11} = \frac{44}{11} - \frac{2}{11} = \frac{44 - 2}{11} = \frac{42}{11}$

So, the results are:

1. $1 - \frac{15}{27} = \frac{4}{9}$
2. $15 - \frac{2}{8} = \frac{59}{4}$
3. $4 - \frac{2}{11} = \frac{42}{11}$
