Answer:
Identify the least common multiple of the denominators found within the equation.
Explanation:
To solve this problem, you need to determine the least common multiple (LCM) of the denominators before adding the fractions.
Detailed explanation:
The given expression is,

Where,
a represents the acceleration of the object, which we aim to find.


m = 7.00 kg
By plugging in these values, the equation is rewritten as,

The two values to be combined are 12/7 and 3; one is a fraction and the other is a whole number.
Adding these requires finding a shared denominator, which lies beneath the division line in a fraction.
For 12/7, the denominator is 7; for 3, considered as 3/1, the denominator is 1.
To find a common denominator for these fractions, calculate the least common multiple of 7 and 1.
The least common multiple is the smallest number divisible by both denominators fully.
Here, the LCM is 7.
Thus, 7 becomes the common denominator.
- Look at
. Since its denominator is already 7, no changes are needed.
- For 3, convert the denominator from 1 to 7 by multiplying the denominator by 7, and also multiply the numerator by 7.

Now that the denominators match, we can sum the fractions like this,

Hence, the result is,
