144 members are at a meeting, which is 90% of the total group.

Answer 1

If 144 members represent 90% of the total group, we can determine the total number of members in the group by setting up the following equation:

Let \( x \) be the total number of members in the group.

\[ 0.90x = 144 \]

To find \( x \), divide both sides of the equation by 0.90:

\[ x = \frac{144}{0.90} \]

\[ x = 160 \]

So, the total number of members in the group is 160.
