13/250 = 13*4/250*4 = 52/1000 = 0.052
Answer:
1:3
Step-by-step explanation:
The total animals is 45 and the cats is 15.
The ratio is 15:45
Simplified, it would be 1:3 because you can divide each side my 15.
Hope this helped!! :)

Answer:
Supermarket gets 300 cupcakes.
Step-by-step explanation:
Given,
Total cupcakes = 525,
Since, the ratio of bakery and supermarket cupcakes = 3 : 4,
Let the bakery cupcakes = 3x and supermarket cupcakes = 4x
Where x is any positive real number.
So, the total cupcakes = 3x + 4x = 7x
Divide both sides by 7,
Hence, the supermarket cupcakes = 4(75) = 300
Answer:
Step-by-step explanation:
We can let b and c represent the cost of a book and the cost of a CD, respectively. Then the purchases can be described by ...
3b +7c = 79
5b +2c = 35
Using Cramer's rule to find the solution, we have ...
b = (7(35)-2(79))/(7(5) -2(3)) = 87/29 = 3
c = (79(5)-35(3))/29 = 290/29 = 10
The cost of each book was $3; the cost of each CD was $10.
_____
Cramer's rule tells you the solution to ...
ax +by = c
dx +ey = g
is ...
x = (bg -ec)/(bd -ea)
y = (cd -ga)/(bd -ea) . . . . same denominator
This solution is fully equivalent to using elimination or substitution to solve the problem. Using these formulas effectively "cuts to the chase" without all the intermediate steps. The cross-multiplying pattern of differences is not hard to memorize.
