Пошаговое объяснение:

-1  3/7×(-4  1/5 ) = -1 3/7*4 1/5=3 + 1·7/7*1+4*5/5=10/7×21/5=10*21/7*5=210/35= 6*35/35=6

Answer 3

To solve the expression, we need to convert the mixed numbers to improper fractions and then perform the multiplication:

-1 3/7 = -1 + 3/7 = -7/7 + 3/7 = -10/7

-4 1/5 = -4 + 1/5 = -20/5 + 1/5 = -19/5

Now we can multiply the two fractions:

(-10/7) * (-19/5) = (10/7) * (19/5) [Multiplying by -1 on both sides to simplify]

= (10 * 19) / (7 * 5) [Multiplying the numerators and denominators]

= 190 / 35

To simplify the fraction, we can find the greatest common divisor (GCD) of 190 and 35, which is 5:

190 / 35 = (190 ÷ 5) / (35 ÷ 5) = 38 / 7

Therefore, the result of the expression -1 3/7 * (-4 1/5) is 38/7.
