Answer: the number is 3
Step-by-step explanation:
since you sat one number if four times another number i thought
[tex]\frac{4}{1} = \frac{12}{5} \\as 4 times 3 gives you 12[/tex]
so the missing numbers would be 1 and 4
not sure if im right though
One number is 3 and another number is 12
Assume;
One number = a
Another number = 4a
Sum of reciprocal = 5 / 12
So,
1/a + 1/4a = 5 / 12
[4a + a] / 4a² = 5 / 12
[5a] / 4a² = 5 / 12
5 / 4a = 5 / 12
20a = 60
a = 3
One number = a = 3
Another number = 4a = 4(3) = 12
