Let
x------> Cathy's<span> ages
</span>y------> Tony's ages

we know that
x+y=65-----> x=65-y-----> equation 1
y-8=(2/5)*(x-8)-----> equation 2

substitute equation 1 in equation 2
y-8=(2/5)*(65-y-8)---> y-8=22.8-0.4y----> y+0.4y=22.8+8
1.4y=30.8-----> y=22
x=65-y-----> x=65-22----> x=43

the answer is
Cathy's ages is 43 years
Tony's ages is 22 years

There are 4 sports stores,9 clothing stores and 6 jewelry stores ina shopping crnter which ratio compares the number of sports s

Pani-rosa [81]

The ratio is 2 : 9

Step-by-step explanation:

Given:

The number of sports store = 4

The number of clothing store = 9

The number of jewellery stores = 5

To Find :

The ratio of number of sports stores to the total number of stores

Solution:

The ratio of number of sports stores to the total number of stores

= $\frac{\text{number of sports store}}{\text{ Total number of stores}}$

The total number of stores = number of sports store + number of clothing store + number of jewellery store

The total number of stores = 4 + 9 + 5

The total number of stores = 18

Now the ratio is

= $\frac{4}{18}$ or 4 : 8

The ratio after reduction is

= $\frac{2}{9}$ or 2 : 9 or 2 to 9
