Explicación paso a paso:

Multiplica el número de vueltas por la constante, la cual equivale a 12, la longitud de una vuelta. 12 x 2 = 24

12 x 1 ½ = (12 x 1) + [(12 x 1) ÷ 2] = 12 + (12 ÷ 2) = 12 + 6 = 18

12 x ½ = (12 x 1) ÷ 2 = 12 ÷ 2 = 6

12 x 2/3 = (12 x 2) ÷ 3 = 24 ÷ 3 = 8

12 x 2 ¼ = (12 x 2) + [(12 x 1) ÷ 4] = 24 + (12 ÷ 4) = 24 + 3 = 27

12 x 1/3 = (12 x 1) ÷ 3 = 12 ÷ 3 = 4

12 x 1 2/3 = (12 x 1) + [(12 x 2) ÷ 3] = 12 + (24 ÷ 3) = 12 + 8 = 20

12 x 2 1/3 = (12 x 2) + [(12 x 1) ÷ 3] = 24 + (12 ÷ 3) = 24 + 4 = 28

Explición paso a paso:

Multiplica el número de vueltas por la constante, la cual equivale a 12, la longitud de una vuelta. 12 x 2 = 24

12 x 1 ½ = (12 x 1) + [(12 x 1) ÷ 2] = 12 + (12 ÷ 2) = 12 + 6 = 18

12 x ½ = (12 x 1) ÷ 2 = 12 ÷ 2 = 6

12 x 2/3 = (12 x 2) ÷ 3 = 24 ÷ 3 = 8

12 x 2 ¼ = (12 x 2) + [(12 x 1) ÷ 4] = 24 + (12 ÷ 4) = 24 + 3 = 27

12 x 1/3 = (12 x 1) ÷ 3 = 12 ÷ 3 = 4

12 x 1 2/3 = (12 x 1) + [(12 x 2) ÷ 3] = 12 + (24 ÷ 3) = 12 + 8 = 20

12 x 2 1/3 = (12 x 2) + [(12 x 1) ÷ 3] = 24 + (12 ÷ 3) = 24 + 4 = 28
