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>

ANSERR GIVE ME ANSWERS PLS
Zarrin [17]

Answer:

Concept: Mathematics

When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.

  1. 1.365 × 10^1
  2. You see its positive 1 hence we move one space to the right
  3. Our answer is now 13.65

You keep doing the same thing

  1. 1.365 × 10^2
  2. 136.5

Lastly

  1. 1.365 ×10^3
  2. 1365

Rate positively and give 5 stars
