I thought of a number, multiplied it by 2 1/2 , divided the result by 1 1/5 , subtracted 7/18 from it, and got 1 5/6 . What was
motikmotik

To figure out what the number is, just do the inverse operations in the opposite order:

Start by adding 7/18 to 1 5/6, which gives you 2 2/9.

Next, multiply 2 2/9 by 1 1/5, which gives you 2 2/3.

Finally, divide 2 2/3 by 2 1/2, which gives you 1.06666...

Therefore, the number you thought of is 1.06666...

<em>Hope this helps! :)</em>

x = 13.5 m - 7.5m / 2
= 6/2
= 3 m

Therefore x = 3 m

y = a^2=b^2 + c^2
= a^2 = 9^2 + 3^2
= a^2 = 90
= a = 9.5m

Therefore y = 9.5m

Perimeter = a+b+c+d
= 9.5 + 9.5 + 7.5 + 13.5
= 40m

Area= a+b/2 h
= 7.5+13.5/2 x 9
= 94.5 m^2


Kite
Area= p x q /2
= 12 x 9 /2
= 54 m^2

One half divided by two fifths
kramer
1/2 divided by 2/5

In order to get the correct answer you need to flip the second fraction and then multiply it with the first fraction so it will stay like this:

1/2 x 5/2

To find the answer you need to multiply 1 x 5= 5 and 2 x 2=4 which will give you the final answer which is:

5/4 as improper fraction or it can also be 1 1/4 as mixed number, both are correct.
