let the number be x
0.75x=1200
75/100x=1200
x=1200*100/75=1600

5/8 of 1600
=1000

Answer 2

5/8 of the number, 1600 is 1000.

Let the unknown number be x

As given, 0.75 of a number is 1200 ( here 'of' refers to multiplication)

So, 0.75* x = 1200

Or, 0.75 x = 1200

Or, (75/100) x = 1200

Therefore, x =( 1200*100)/75= 1600

So, the value of the unknown number is 1600

Now we are asked to find out:

5/8 of 1600 which is equal to 1000.
