# There are 144 people in an audience. The ratio of adults to children is 3:5. How many adults are there?

$54$
ratio is $3 : 5$ so consider that $8$ parts all together
$\frac{144}{8} = 18$ so each part has $18$ people
$3$ parts are adults so $3 \cdot 18 = 54$ of them
and $5$ parts are children so $5 \cdot 18 = 90$ of them
