Question

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 my number? HELP ASAP

Answer 1

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...

Hope this helps! :)
