Question

Умножение г)-4 3/8*(-4/21)

Answer 1

-4 3/8*(-4/21)=-35/8*(-4/21)=5/6

Answer 2

To multiply two fractions, you simply multiply their numerators together to get the new numerator, and multiply their denominators together to get the new denominator. The resulting fraction will be in its simplest form.

Let's calculate the multiplication of the given fractions:

First, convert the mixed number -4 3/8 to an improper fraction: -4 3/8 = -4 + 3/8 = -4 + 3 * (1/8) = -4 + 3/8 = -32/8 + 3/8 = (-32 + 3)/8 = -29/8

So, the expression becomes:

(-29/8) * (-4/21)

Now, multiply the numerators and denominators:

Numerator: (-29) * (-4) = 116 Denominator: 8 * 21 = 168

The result of the multiplication is:

116/168

Now, you can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 116 and 168 is 4:

116 ÷ 4 = 29 168 ÷ 4 = 42

So, the simplified fraction is:

29/42
