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)

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
espero haberte ayudado
