​

Answer 1

2 1/2 + 4 1/5

= 5/2 + 21/5

= 5(5)/2(5) + 21(2)/5(2)

= 25/10 + 42/10

= (25 + 42)/10

= 67/10

= 6 7/10

= 0,67

Answer 2

2 ½ + 4 ⅕ = ...

= 2 + 4

= 6

½ + ⅕

= x/10 + x/10

= (10 ÷ 2 × 1)/10 + (10 ÷ 5 × 2)/10

= 5/10 + 4/10

= 9/10

6 + 9/10

= 6 9/10

5/2 + 21/5

= (10 ÷ 2 × 5)/10 + (10 ÷ 5 × 21)/10

= 25/10 + 42/10

= 67/10

= 6 7/10
