Vincent and Aidan buy the same number of pens. Vincent buys packs of 6 pens, and Aidan buys boxes of 20 pens. What is the least
Shtirlitz [24]

The least number of pens each boy can have brought is 60

<h3>How to determine the least number of pen?</h3>

We have:

Vincent = 6 packs

Aidan = 20 boxes

Factorize 6 and 20

6 = 1 * 2 * 3

20 = 1 * 2 * 2 * 5

Multiply all factors

LCM = 1 * 2 * 2 * 3 * 5

Evaluate the product

LCM = 60

Hence, the least number of pens each boy can have brought is 60

Which of the following is a measurement conversion that you may need to make when comparing energy and mass in nuclear reactions
DiKsa [7]
The correct option is C. In Nuclear reactions, two nuclear particles collide to produce products that are different from the reactants. During nuclear reaction, a lot of processes take place. In nuclear reactions, the total energy is conserved. Thus, the missing rest mass energy can be accounted for by using the Einstein's formular  to find mass - energy equivalence.
