Answer 2

Sure, I can show you 90÷5 in different ways:

1. Long Division Method:

   luaCopy code
       18
    __________
   5 | 90
       - 85
       -----
          5
   

2. Repeated Subtraction Method:

   Copy code
   90 - 5 = 85
   85 - 5 = 80
   80 - 5 = 75
   75 - 5 = 70
   70 - 5 = 65
   65 - 5 = 60
   60 - 5 = 55
   55 - 5 = 50
   50 - 5 = 45
   45 - 5 = 40
   40 - 5 = 35
   35 - 5 = 30
   30 - 5 = 25
   25 - 5 = 20
   20 - 5 = 15
   15 - 5 = 10
   10 - 5 = 5
   5 - 5 = 0
   

3. Grouping Method: Split 90 into groups of 5:

   Copy code
   5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 90
   

4. Multiplication Method:

   Copy code
   5 * 18 = 90
   

5. Shortcut Division: Since 5 goes evenly into 90, the result is simply:

   Copy code
   90 ÷ 5 = 18
   

6. Fraction Representation:

   Copy code
   90 ÷ 5 = 18/1
   

7. Using Decimals:

   Copy code
   90 ÷ 5 = 18.0
   

8. Exponential Representation:

   Copy code
   90 ÷ 5 = 1.8e+1
   

9. Binary Division:

   phpCopy code
   1011010 ÷ 101 = 10010 (in binary)
   

10. Roman Numerals: 90 is represented as XC in Roman numerals, and 5 is represented as V, so:

    javaCopy code
    XC ÷ V = XVIII
    

Remember, all these methods will give you the same result: 18.
