Answer:
5 times
Step-by-step explanation:
Assume the height of the streetlamp to be x
If you make a diagram from the details given by the question you should find two pairs of similar sides, from which you can form the equation

Solving this gives the height of the streetlamp as 30 feet. Divide this length by the height of the man to get the number of times the streetlamp is taller.
to simplify it just find a number that goes into both numbers, in this occasion its 5
so divide each number by 5;
25 ÷ 5 = 5
30 ÷ 5 = 6
so 25/30 in simplest form is: 5/6
Hope that helps :D
If u multiply and simplify the answer is 1/16.
Well if he puts 6 on each of the 5 notebooks, you'd do 5*6 and get 30. If 10 are on each sheet you'd do 30/10 & end up with 3 sheets of stickers :)
<u>(5/6) times 'z' = 85</u>
Multiply each side by 6 :
5 z = 510
Divide each side by 5 :
<u>z = 102</u>
Tough one !
