Answer 1

Ответ:

$4\frac{1}{5} : (-\frac{7}{15}):\frac{1}{3} = -27$

$1)4\frac{1}{5} : (-\frac{7}{15})= -(\frac{21*15}{5*7} )=-(3*3)=-9$

$2)-9:\frac{1}{3} =-\frac{9*3}{1} =-9*3=-27$

Answer 2

To solve this expression, let's first convert all the fractions into a common denominator.

The common denominator for 1/5, -7/15, and 1/3 is 15. So, we have:

4 1/5 : (-7/15) : 1/3 = (4 * 15/15) : (-7/15) : (1/3) = (60/15) : (-7/15) : (1/3) = 60/15 : -7/15 : 1/3

Now, let's simplify the expression:

= (60/15) / (-7/15) / (1/3) = (60/15) * (15/-7) * (3/1) = (60 * 15 * 3) / (15 * -7 * 1) = (3 * 3 * 5 * 2 * 2 * 5) / (3 * 5 * -7 * 1) = (3 * 2 * 2 * 5) / (-7) = (60) / (-7) = -60/7

Therefore, the answer is -60/7.
