When two fractions with different denominators are to be added using the standard procedure, which of these must first be found?

Select right answer

1.The GCF (Greatest Common Factor) of the fractions

2.The prime factorization of the fractions’ numerators

3.The LCD (Least Common Denominator) of the fractions

4.The mean value of the denominators

3. The LCD (Least Common Denominator) of the fractions

Step-by-step explanation:

This is the first step to do in order to be able to properly add the fractions.

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.
