Dividing a 2-digit number by 625
Select a 2-digit number.
Multiply by 8.
Divide the product by 5.
Move the decimal point 3 places to the left.
Example:
The 2-digit number chosen to divide by 625 is 65.
Multiply by 8: 8 x 65 = 480 + 40 = 520
Divide by 5: 520/5 = 104
Move the decimal point 3 places to the left: .104
So 65 divided by 625 = .104.
See the pattern?
The 2-digit number chosen to divide by 625 is 32.
Multiply by 8: 8 x 32 = 240 + 16 = 256
Divide by 5: 256/5 = 51.2
Move the decimal point 3 places to the left: .0512
