**the correct order is**

**0.33 , 3.003, 3.033, 3.3, 3.303**

**see, when you have some confusion in this equal the number of digits after the decimal point.**

**for eg:**

**0.33 = 0.330**

**3.003 = 3.003**

**3.033 = 3.033**

**3.3 = 3.300**

**3.303 = 3.303**

**for equalising the digits, keep on putting zeroes unless we have the LCM no. of zeroes.**

**now, we have equal no. of digits after the decimal , i.e., three.**

**now check for the ones place.**

**0 is small so 0.33 will get the first place.**

**now, all others have same ones place 3.**

**so, look for the digits after the decimal.**

**arrange the no.s in the order of increasing numbers after the decimal.**

**like, 3, 33, 300, 303.**

**so, the increasing order will be 3.003, 3.033, 3.3, 3.303.**

**so, the answer key is correct.**

**or a more simpler way is multiply the numbers by 1000.**

**so you get,**

**3300, 3303, 3033, 330, 3003**

**no arrange them in ascending order:**

**330, 3003, 3033, 3300, 3303**

**now again divide by thousand and put decimals and get the order.**

**hope it helps!!**

**cheers!!!**
