Question

You have an stick that is 25x long. 23 is 7/25th of the length. What is the length?

Answer 1

• Length=25x

ATQ

`\\ \sf\longmapsto (7)/(25)\:of\:25x=23`

`\\ \sf\longmapsto (7)/(25)* 25x=23`

`\\ \sf\longmapsto 7x=23`

`\\ \sf\longmapsto x=(23)/(7)`

Now

Length=

`\\ \sf\longmapsto 25x`

`\\ \sf\longmapsto (25(23))/(7)`

`\\ \sf\longmapsto (575)/(7)`

Answer 2

• 82 1/7 units

Explanation:

The length is 25x and 7/25th of the length is 23:

• 7/25*25x = 23
• 7x = 23
• x = 23/7

The length is:

• 25*23/7 = 575/7 = 82 1/7 units
