The ratio of adult cats to kittens at a pet care center on Thursday was 5:4. There were 16 kittens there that day. Monday, 27 adult cats were at the pet care center. What is the difference between the number of adult cats at the pet care center on Monday and Thursday?
+591 Because the ratio is 5:4, there are 5/4 times as many adult cats as kittens, or 4/5 times as many kittens than adult cats. so we have
$16\cdot\frac54=20$
$27-20=\boxed{7}$
