10/6-2/3=
​

Answer 1

Respuesta:

2/5+7/6 = 47/30

2/5+7/6 =

(2(6)+5(7))/(5×6)

= (12+35)/30

= 47/30

4/3+8/4 = 10/3

4/3+8/4

= (4(4)+3(8))/(3×4)

= (16+24)/12

= 40/12

= ( 40÷4 )/( 12÷4 )

= 10/3

6/2-3/4 = 9/4

6/2-3/4

= (6(4)-2(3))/(2×4)

= (24-6)/8

= 18/8

= ( 18÷2 )/( 8÷2 )

= 9/4

10/6-2/3 = 1

10/6-2/3

= (10(3)-6(2))/(6×3)

= (30-12)/18

= 18/18

= 1
