If 2/5 of a number exceeds 1/7 of the same number by 36.
Find the number.
Jonasmathwork wrote:Solution: Let the number is x
then 2/5 of x=2x/5
x exceeds 1/7 of number 36
there for the equation 2x/5=x/7+36
2x/5-x/7-36=0
9(x-140)/35=0
x=140
the number is 140.

Let the required number be x.
[tex]\frac{2}{5} * x = \frac{1}{7} * x + 36[/tex]
[tex]\frac{2}{5} * x - \frac{1}{7} * x = \frac{14}{35} * x - \frac{5}{35} * x = \frac{9}{35} * x = 36[/tex]
[tex]x = 36 * \frac{35}{9} = 4 * 35 = 140[/tex]
Answer: [tex]x = 140[/tex]
