USE PROPERTIES OF RATIONAL NUMBERS TO MULTIPLY THE FOLLOWING
-14/5 X (-51/69)
To multiply rational numbers, we multiply the numerators and denominators separately.
The given expression is:
(-14/5) * (-51/69)
Multiplying the numerators:
(-14) * (-51) = 714
Multiplying the denominators:
(5) * (69) = 345
Therefore, the result of the multiplication is:
(-14/5) * (-51/69) = 714/345
However, we can simplify this fraction further by finding the greatest common divisor (GCD) of 714 and 345, which is 3.
Dividing the numerator and denominator by 3:
714/3 = 238
345/3 = 115
So, the simplified form of the expression is:
(-14/5) * (-51/69) = 238/115
