Answer 1

Respuesta:

Explicación paso a paso:

4/5 + 6/8=

= 4 /5 + 3 /4

= 31 /20

9/18 +3/2=

= 1 /2 + 3 /2

=2

9/8 + 12/4=

= 9 /8 +3

= 33 /8

12/5 + 9/10=

= 24 /10 + 9 /10

= 24+9 /10

= 33 /10

10/4 + 12/8=

= 5 /2 + 12 /8

= 5 /2 + 3 /2

=4

12/10 +4/20=

= 6 /5 + 4 /20

= 6 /5 + 1 /5

= 7 /5

7/6 - 3/4=

= 7 /6 + −3 /4

= 14 /12 + −9 /12

= 14+−9 /12

= 5 /12

17/10 - 4/20=

= 17/ 10 − 1 /5

= 3 /2

9/4 - 3/9=

= 9 /4 − 1 /3

= 23 /12

6/4 - 8/12=

= 3 /2 − 8 /12

= 3 /2 − 2 /3

= 5 /6

8/4- 9/16=

=2−   9 /16

= 23 /16

5/2 - 8/10=​

= 5 /2 − 4 /5

= 17 /10

SUERTE!!

Explicación paso a paso:

-4/5+6/8= 16+15/20= 31/20

9/18 + 3/2 = 1/2 + 3/2 = 4/2=2

12/5 + 9/10= 24+9/10=33/10
