Answer:
The ratio is 1:3
Step-by-step explanation:
Let
x -----> the number of tables in the restaurant
y ----> the number of chairs in the restaurant
we know that
To find out the ratio of tables to chairs in the restaurant, divide the number of tables by the number of chairs
we have
![x=18\ tables\\ y=54\ chairs](https://tex.z-dn.net/?f=x%3D18%5C%20tables%5C%5C%20y%3D54%5C%20chairs)
so
The ratio is equal to
![\frac{18}{54}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B54%7D)
Simplify
Divide by 18 both numerator and denominator
![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
therefore
The ratio is 1:3
Answer:
<em>Peter now has 54 baseball cards</em>
Step-by-step explanation:
<u>Percentages</u>
Assume Peter had x baseball cards in his collection. The 35% of his initial collection is
35 * x / 100= 0.35x
We know that those 14 new baseball cards represent a 35% of his previous collection, therefore we can set a simple equation
0.35x=14
When we solve for x, we'll know how many baseball cards Peter had before
x=14 / 0.35 = 40
Peter had 40 cards, he added 14 new baseball cards, so he now has 40+14=54
Peter now has 54 baseball cards
