Minta tolong yaa , besok mau di kumpul soalnya ​

• No. 4

= ( - 3/5 ) + ( - 4/5 )

= -( 3 + 4 )/5

= - 7/5

= - 1 2/5

• No. 5

= ( - 1/2 ) + ( - 3/4 )

= ( - 1/2 × 2/2 ) + ( - 3/4 × 1/1 )

= ( - 2/4 ) + ( - 3/4 )

= - ( 2 + 3 )/4

= - 5/4

= - 1 1/5

• No. 6

= 1/4 + ( - 5/6 )

= ( 1/4 × 3/3 ) + ( - 5/6 × 2/2 )

= ( 3/12 ) + ( - 10/12 )

= - ( 10 - 3 )/12

= - 7/12
