The sign of the product -2/9 * 1/7 is - (negative).
Well, let's do the math to determine the sign of the product. We have -2/9 multiplied by 1/7. So, when we multiply these two fractions, the negative signs cancel each other out, leaving us with a positive result. Therefore, the sign of the product is + (positive).
To determine the sign of the product (-2/9) * (1/7), we can simplify the expression first.
(-2/9) * (1/7) = (-2 * 1) / (9 * 7) = -2/63
Since the product is -2/63, the sign is negative, so the answer is - (negative).
To determine the sign of the product -2/9 * 1/7, we need to multiply the two fractions.
The product of two fractions has a positive sign (+) if both fractions have the same sign, either positive or negative. And it has a negative sign (-) if the two fractions have different signs.
In this case, -2/9 is negative (-) because the numerator is negative, and 1/7 is positive (+) because both the numerator and denominator are positive.
Since the two fractions have different signs, their product will be negative (-).
Thus, the sign of the product -2/9 * 1/7 is (-) negative.
