4 0

To solve this question, first cross multiply
Let ? = x

4/9 = x/81

4(81) = 9(x)

Simplify.

81 x 4 = 324

324 = 9x

Isolate the x, divide 9 from both sides

324/9 = 9x/9

x = 324/9

x = 36

4/9 = 36/81

36 is your answer

hope this helps!

How do I write the sum of two numbers as the product of their GCF and another sum

Delicious77 [7]

Let's assume we were given 2 numbers: 15 and 30. Their sum is:
$15+30 = 45$
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
$\frac{15}{15} = 1$
$\frac{30}{15} = 2$
In this case sum of two numbers can always be written as:
$15+30 = (15\cdot 1) + (15\cdot 2) = 15\cdot (1+2) = 15\cdot 3 = 45$
