An inch is defined, strangely enough, as 2.54 cm. There are 100 cm in a metre. So 300cm is 3 metres.

Setting up the ratio, we have

1 inch = x inches

-------- -----------

2.54cm 300cm

Next, we cross multiply and get 2.54 x x = 300.

Dividing both sides by 2.54 to get x by itself.

I get 118.11". There are 12 inches in a foot, so we get 9 feet. Subtracting 108" (9x12) from the 118.11", we get 10.11" left over, so 3 metres is 9 feet 10.11 inches.

Good luck.

(-9/3)x=-2

First simplify -9/3 to -3 : -3x=-2

Divide by -3.

x=-2/-3=2/3

First simplify -9/3 to -3 : -3x=-2

Divide by -3.

x=-2/-3=2/3

There are multiple answers right to this question. You can even interchange the numbers (up and down) in the given answer to obtain a new answer.

Now... how did I figure it out...

The best technique to solve this problem is trial-and-error, and not to use the brain much. If you use your brain to solve this problem, then there is no way this problem can be solved.

Ok,

I willl simulate the thought process that goes into solving this kind of problems. I trust you will adapt it to your way of thinking.

Question: How much did he walk?

Answer: Nine times around the lake. To find the total distance I need the length of one single lap

**Total distance = 9 times the length of a path around the lake.**

I cannot go further until I find the length of the path around the lake

Shape pf path : circle

**Circumference of a circle = diameter x π =π*D**

I know the diameter and I need π. I will use the suggested approximate value 3.

Solution

Length of one lap = 3*5 m = 15 m

Total distance = 9 * 15 m = 135 m

Hope I did not bore you with things you already knew.

Hope it helps.

Thank you for using FixYa.

P.S. A lake with a 5 m diameter is not nuch of a lake. Shouldn't we call it a large puddle?

One way to solve this is:

Start at 108, which is the first 3 digit number divisible by both 12 and 9.

Then continue adding twelve until you find a number which matches all your criteria.

You will find the answer to be 180.

180 / 12 = 15

180 / 9 = 20

0 < 8

The two numbers 3 and 24

3 multiplied by 24 =72

24 divided by 3 =8

Enjoy, and thanks for choosing Fixya!
