Answer:

I will answer in English, you can translate it after, as this is math, will be easier to read.

This can be translated to:

Present the fraction:

a) - 7/9 as a fraction with 27 denominator

b) 7/17 as a fraction with 102 denominator

c) 13/16 as a fraction with 80 denominator

d) 11/13 as a fraction with 78 denominator

a) We can multiply both numerator and denominator by the same number, and the quotient remains the same:

We know that 9*3 = 27

then: (-7/9)*(3/3) = -21/27

b) Here we can use that 102 = 17*6

Then we multiply the numerator and denominator by 6:

(7/17)*(6/6) = 42/102.

c) We can use that 16*5 = 80.

Then we should multiply both denominator and numerator by 5.

(13/16)*(5/5) = 65/80

d) We can use that 6*13 = 78, then we can multiply both denominator and numerator by 6.

(11/13)*(6/6) = 66/78

Answer:

x = 2

y = -3

z = 4

( 2 , -3, 4 )

Step-by-step explanation:

x + y + z = 3 ---- i

x – y =5 ---- ii

y - z = -7 ---- iii

ii + iii

x - z = -2 ---- iv

i + ii

2x + z = 8 --- v

iv + v

3x = 6

x = 2

x=2 substitute for v

z = 4

x =2 substitute for ii

y = -3
