Пошаговое объяснение:

$\displaystyle \tt 3\frac{4}{5} :5\frac{7}{10} =\frac{19}{5} :\frac{57}{10} =\frac{19*10}{5*57} =\frac{1*2}{1*3} =\frac{2}{3}$

Answer 2

To perform the operation of division between 3 4/5 and 5 7/10, follow these steps:

Step 1: Convert both mixed numbers to improper fractions.

• 3 4/5 as an improper fraction is (5 * 3 + 4) / 5 = 19/5.
• 5 7/10 as an improper fraction is (10 * 5 + 7) / 10 = 57/10.

Step 2: Divide the first fraction by the second fraction.

• (19/5) ÷ (57/10)

Step 3: Invert the second fraction (reciprocal) and multiply.

• (19/5) * (10/57)

Step 4: Simplify the fraction if possible.

• First, reduce both fractions if possible. In this case, you can divide both the numerator and denominator of the second fraction by their greatest common divisor, which is 1:
  • (19/5) * (10/57) = (19/5) * (10/57) = (19/5) * (10/57)

Now, multiply the numerators together and the denominators together:

• (19 * 10) / (5 * 57)

Step 5: Calculate the result:

• (190) / (285)

Step 6: Simplify the fraction further if possible. Both the numerator and denominator can be divided by their greatest common divisor, which is 5:

• (190/5) / (285/5) = 38/57

So, 3 4/5 divided by 5 7/10 is equal to 38/57 when expressed as a fraction in simplest form.
