Question

1 2/3*2 1/5=вычислить

Answer 1

12/3*21/5=12*7/5=84/5=16,8

Answer 2

1 2/3*2 1/5= 11/3
1 2/3* 2 1/5= 5/3*11/5=11/3

Answer 3

To multiply these two mixed numbers, we first need to convert them to improper fractions.

Converting 1 2/3 to an improper fraction: 1 2/3 = (1 * 3 + 2)/3 = 5/3

Converting 2 1/5 to an improper fraction: 2 1/5 = (2 * 5 + 1)/5 = 11/5

Now, we can multiply the two improper fractions:

5/3 * 11/5 = (5 * 11)/(3 * 5) = 55/15

We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 5:

55/15 = (11 * 5)/(3 * 5) = 11/3

Therefore, 1 2/3 * 2 1/5 = 11/3 or 3 2/3 when expressed as a mixed number.
