Product of Fractions
To find the product of two fractions, we simply multiply their numerators together and their denominators together.
Formula: (a/b) x (c/d) = (ac/bd)
Solution
Given, 7/8 x -4/21
Multiplying the numerators and denominators, we get
= (7 x -4) / (8 x 21)
= -28 / 168
We can simplify the fraction by dividing both numerator and denominator by their greatest common factor, which is 28.
= -1/6
Therefore, the product of 7/8 and -4/21 is -1/6.
Answer: (a) -1/6
