1-3/8×3 3/7пжпжпжпжп​

Answer 1

Ответ:

$1 - \frac{3}{8} \times 3 \frac{3}{7} = 1 - \frac{3}{8} \times \frac{24}{7} = 1 - 3 \times \frac{3}{7} = 1 - \frac{9}{7} = \frac{7 - 9}{7} = - \frac{2}{7}$

Answer 2

To calculate the product of 1-3/8 and 3 3/7, you first need to convert the mixed numbers into improper fractions and then multiply them. Here's the step-by-step calculation:

1-3/8 = (8 * 1 - 3)/8 = (8 - 3)/8 = 5/8

3 3/7 = (7 * 3 + 3)/7 = (21 + 3)/7 = 24/7

Now, you can multiply these two fractions:

(5/8) * (24/7)

To multiply fractions, you multiply the numerators together and the denominators together:

(5 * 24) / (8 * 7)

Now, calculate the numerator and denominator:

Numerator: 5 * 24 = 120 Denominator: 8 * 7 = 56

So, the product of 1-3/8 and 3 3/7 is 120/56. To simplify the fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 8:

(120/8) / (56/8) = 15/7

So, 1-3/8 times 3 3/7 equals 15/7.
