Answer:
There will be :
210 children in room 1.
350 children in room 2.
STEP BY STEP SOLOUTION + METHOD:
To find the number of children in each room, you can use the ratio as a proportion...
Let the number of children in the first room be = 3x and in the second room be 5x (since the ratio is (3:5).
The total number of children is 3x + 5x = 8x
Given that their are 560 children in this equation, you can set up the equation.
8x = 560
SOLUTION:
8x = 560
[tex] x = \frac{560}{8} [/tex]
70
So, the number of children is in the first room is (3x) is 3 * 70 = 210, and in the second room (5x) is 5 * 70 = 350
