solving rational numbers is so confusing.I don't understand how to solve -14/5 x (-51/69)
(-14 / 5 ) (-51 / 69 )
= (-14 * -51) / (5 * 69)
= 714 / 345
which is
= 2 24/345
which is 2 8/115
To solve the expression -14/5 x (-51/69), you can follow these steps:
Step 1: Simplify the expression.
To simplify the expression, you can multiply the numerators (top numbers) together and multiply the denominators (bottom numbers) together. In this case, you would have:
(-14 x -51) / (5 x 69)
Step 2: Perform the calculations.
To evaluate the expression, you need to multiply the numerators (-14 x -51) and multiply the denominators (5 x 69).
(-14 x -51) = 714
(5 x 69) = 345
Therefore, the expression simplifies to:
714/345
Step 3: Simplify the fraction (if needed).
To simplify the fraction, you can find the greatest common divisor (GCD) of the numerator and denominator and divide both numbers by it.
In this case, the GCD of 714 and 345 is 9.
714 ÷ 9 = 79
345 ÷ 9 = 38
So, the simplified form of the expression is:
79/38
Therefore, -14/5 x -51/69 simplifies to 79/38.
