Answer 1

Respuesta:7/9 − 2 /5

= 7 /9 − 2 /5 = 7 /9 + −2 /5

= 35 /45 + −18 /45

= 35+−18 45

= 17 /45 (Decimal: 0.377778)

(4)(3)+(8)(6)+12

=12+(8)(6)+12

=12+48+12

=60+12

=60+1

=6

6/ 8 −3/4

= 3/4 −34

= 3 /4 −81

= −321/ 4 (Decimal: 80.25)

9/ 12 − 2 /3

= 9 /12 − 2 /3

= 9 /12 + −2 /3

= 3 /4 + −2 /3

= 9 /12 + −8/ 12

= 9+−8/ 12

= 1 /12 (Decimal: 0.083333

2/ 5 + 4 /3 + 6 /10

= 26/ 15 + 6 /10

= 26 /15 + 3 /5

= 7 /3 (Decimal: 2.333333)

Answer 2

Explicación paso a paso:

7/9 - 2/5  

= 35 - 18/45

= 17/45

4/3 + 8/6 + 1/2  

= 4/3 + 4/3 + 1/2  

= 4 + 4/3 + 1/2

= 8/3 + 1/2

= 16/6 + 3/6

= 16 + 3/6

= 19/6

6/8 - 3/4  

= 3/4 - 3/4

= 3 - 3/4

= 0/4

= 0

9/12 - 2/3  

= 3/4 - 2/3  

= 9/12 - 8/12

= 9 - 8/12

= 1/12

2/5 + 4/3 + 6/10  

= 2/5 + 4/3 + 3/5

= 2 + 3/5 + 4/3  

= 5/5 + 4/3  

= 1 + 4/3

= 3 . 1/3 + 4/3

= 3/3 + 4/3

= 3 + 4/ 3

= 7/3
