One number is 4 times another. If the sum of their reciprocals is 5/36 , find the two numbers.
I am total lost on this problem
x is a number
4x is another number
these should = 5/36
so my equation would be
x+4x=5/36
first x i am getting 1/36
so the second would be 4/36=9
the two numbers be 1/36, 9
please explain to me what i have done wrong
the sum of their RECIPROCALS. which isn't x+4x
reciprocal of 5/36 is 36/5=7.2
does this mean my answers to add to
x =4x=7.2
please explain this to me
One number is 4 times another. If the sum of their reciprocals is 5/36 , find the two numbers.
x = 2y
1/x + 1/y = 5/36
You should be able to take it from here.
