✔ 最佳答案

2 x 2 3/5

= 2 * ( 2 + 3/5 )

= 2 * ( 13/5)

= 26 / 5

= 5 + 1/5

= 5 1/5

2(2 3/5) = 5 1/5
2(13/5) = 26/5
26/5 = 26/5

Answer: Yes, they are.

2 and 3/5 is equal to 13/5
when multiplied by 2 = 26/5
26/5 = remainder 1, quotient 5 so = 5 and 1/5

2 x 2 3/5
= 2 x (2 + 3/5)
= 2 x (10/5 + 3/5)
= 2 x 13/5
= 26/5
= (25 + 1)/5
= 25/5 + 1/5
= 5 1/5
