Answer:

the exact answer is 2 1522/1529. sadly this cannot be simplified

Answer:

  2 1522/1529 ≈ 2.995422

Step-by-step explanation:

Division of mixed numbers with different denominators is often best done by converting each to an improper fraction. Then, the division can be accomplished by multiplying the dividend by the reciprocal of the divisor.

  20 9/11 = (20∙11 +9)/11 = 229/11

  6 19/20 = (6∙20 +19)/20 = 139/20

The division problem then becomes ...

  20 9/11 ÷ 6 19/20 = (229/11) × (20/139) = (229∙20)/(11∙139)

  = 4580/1529 = 2 1522/1529
