What is 19/25 as decimal

Radda [10]

Well first we need to find how we can turn 25 into 100
Well one way would be to multiply by 4
25 x 4 = 100

Since we multiplied the bottom number by 4 we should multiply the top number by 4.

So..
19 x 4 = 76

So our new fraction is..
76
-----
100

Now we can easily turn this into a decimal.
76/100 = 0.76

Answer = 0.76

Good Luck! :)

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 9 dogs and made a total of $51. Ho

Shalnov [3]

Use a system of equations.

(x=# of small dogs, y=# of big dogs)

x+y=9 (times by -5) -5x-5y=-45
5x+8y=51

Then add the equations together and the x's cancel.

3y=6
y=2

So he walked 2 big dogs and 7 little dogs.
