Question

The product of four numbers is 540 three of the numbers are 25 and 9 find the other number

Answer 1

To find the fourth number when the product of four numbers is 540 and three of the numbers are 25 and 9, we can set this up as follows:

Let the fourth number be \( x \).

The equation can be written as:
\[
25 \times 9 \times x = 540
\]

First, we calculate \( 25 \times 9 \):
\[
25 \times 9 = 225
\]

Now substitute this back into the equation:
\[
225 \times x = 540
\]

To find \( x \), divide both sides by 225:
\[
x = \frac{540}{225}
\]

Next, simplify the fraction:
\[
x = \frac{540 \div 45}{225 \div 45} = \frac{12}{5}
\]

So, the fourth number is:
\[
x = 2.4
\]

Thus, the other number is \( \mathbf{2.4} \).
