By multiplying the same numbers.

2*2=4 *4 square root is 2

3*3=9 *9 square root is 3

4*4=16 *16 square root is 4

5*5=25 *25 square root is 5

Try this, maybe it will work :)

In a bag,There are red and blue cubes in the ratio 4:7.I add 10 more red cubes to the bag.Now here are red and blue cubes in the
Hoochie [10]

Given:

The ratio of red and blue cubes is 4:7.

After adding 10 more red cubes the ratio of red and blue cubes is 6:7.

To find:

The number of blue cubes.

Solution:

The ratio of red and blue cubes is 4:7.

Let the number of red and blue cubes be 4x and 7x respectively.

After adding 10 more red cubes.

Number of red cubes = 4x+10

Then, the ratio of red and blue cubes is 6:7.

\dfrac{4x+10}{7x}=\dfrac{6}{7}

7(4x+10)=6(7x)

28x+70=42x

70=42x-28x

70=14x

Divide both sides by 14.

5=x

Now,

Number of blue cubes in the bag is

7(5)=35

Therefore, the number of blue cubes is 35.
