0.24 is 36% of what number

From the information we have  we know that

36% of that number is 0.24

We find out first what just 1% of the number  will be.

0.24 = 36%  (36% is 0.36 when you remove the percent)

      x = 1 %  (1% is 0.01 when you remove the percent)

where x is 1% of that number.

Cross multiplying the above equation we get:

x × 0.36 = 0.24×0.01

x = 0.024 / 0. 36

so 1% of that number is 0.24  × 0.01 /0.36

Therefore 100% of that number will be:

0.24 × 0.01 / 0.36 × 100 =  0.24/0.36 = 0.66

Therefore the number is 0.66
