Question

6/35*(-25/36) =. 13/24*(-16/39)=. 12/13*26/27=. 17/26*-13=

Answer 1

6/35 · (-25/36) = -(1·5)/(7·6) = -5/42

13/24 · (-16/39) = -(1·2)/(3·3) = -2/9

12/13 · 26/27 = (4·2)/(1·9) = 8/9

17/26 · (-13/1) = -(17·1)/(2·1) = -17/2 = -8 целых 1/2

Answer 2

Let's calculate each expression step by step:

1. $\frac{6}{35} \times \left(-\frac{25}{36}\right)$

$\frac{6}{35} \times \left(-\frac{25}{36}\right) = -\frac{6 \times 25}{35 \times 36}$

$= -\frac{150}{1260}$

$= -\frac{25}{210}$

$= -\frac{5}{42}$

2. $\frac{13}{24} \times \left(-\frac{16}{39}\right)$

$\frac{13}{24} \times \left(-\frac{16}{39}\right) = -\frac{13 \times 16}{24 \times 39}$

$= -\frac{208}{936}$

$= -\frac{26}{117}$

3. $\frac{12}{13} \times \frac{26}{27}$

$\frac{12}{13} \times \frac{26}{27} = \frac{12 \times 26}{13 \times 27}$

$= \frac{312}{351}$

$= \frac{8}{9}$

4. $\frac{17}{26} \times -13$

$\frac{17}{26} \times -13 = -\frac{17 \times 13}{26}$

$= -\frac{221}{26}$

Please note that fractions should be kept in their simplest form, so if needed, we can simplify the fractions further.
