Answer:
400
Step-by-step explanation:
Because 25 is equal to 1/4
So to get the whole number you times it by 4.
The number is 2/9 hope that helps!
It would be 
, or, in simplest form, 
.
You get this by adding all the marbles to find the total number of marbles. <em>10+7+12+9</em>, which equals <em>38</em>.
You have <u>10 red marbles out of 38 total</u>, so that is represented by !
By switching the unknown (x) with the number and seeing if one side really equals the other.
For example, by solving the equation 8/2+3*4+2*X= 10+5*x, we will find that x is the number 2, or that number two is the solution to our equation. To check whether this is true, we have to switch the letter x in the equation with the number 2, so if the results on both sides are the same, our solution is correct.
In this case 8/2+3*4+2*2=10+5*2
Or 4+12+4=10+10
20=20
Which proves that the number 2 is really the solution to the equation.
