german

Answer: $77\ biscuits$

Step-by-step explanation:

For this exercise you need to find the Least Common Multiple (LCM).

The steps two find the Least Common Multiple are shown below:

1. Descompose the numbers into their prime factors.

2. Multiply the commons an non commons with the highest exponent. The product obtained will be the Least Common Multiple.

Knowing this, you can find the Least Common Multiple between 7 and 11. This is:

$7=7\\11=11\\\\LCM=7*11\\\\LCM=77$

Therefore the smallest number of biscuits each must have baked is: $77\ biscuits$
