Question

1. (+8/9)÷(a/b)÷(-1/9)= -80/27

2. (a/b)×(+8/4)= -72/16

3. (+8/9) (a/b)×(3/5)= -7/6​

Answer 1

Respuesta:

Explicación paso a paso:

1. (+8/9)÷(a/b)÷(-1/9)= -80/27

−8b= −80a /27

−216b=−80a

−80a=−216b

−80a /−80 = −216b /−80

a= 27 /10  b

2. (a/b)×(+8/4)= -72/16

2a= −9b /2

4a=−9b

4a /4

= −9b /4

a= −9 /4 b

3. (+8/9) (a/b)×(3/5)= -7/6​

8ax= −35b /2

16ax=−35b

16ax /16x

= −35b /16x

a= −35b /16x
