Answer 1

Answer:

On every 12th day

Step-by-step explanation:

You must find the least common multiple of her schedules.

One way to find the LCM of 4 and 6 is to use the division method.

Write your numbers (4 and 6) in the top row of a table. Then keep dividing them by prime numbers until you can divide no more.

$\begin{array}{ccc}\mathbf{\div} & \textbf{1st No.} & \textbf{2nd No.}\\\mathbf{2} & 4 & 6\\\mathbf{2} & 2 & 3\\\mathbf{3} & & 1\\\end{array}$

The LCM is the product of the numbers in the first column.

LCM = 2 ×3 × 3 = 12

Gabriella will be volunteering for both the hospital and the food pantry on Day 12 and every 12th day afterwards.

The number line below shows that the first time her volunteering coincides is Day 12.
