The answer to the question of what can you multiply to 5 to get 9 is 4.
125
MULTIPLY BY 1.05 TO INCREASE BY 5%
You don't multiply by the second number, you multiply by the recipricol. For example, 5/8 divided by 3/5... you multiply 5/8 by 5/3. Which would give you 25/24ths, or 1 and 1/24.
You multiply 20 by 5 to get 100

1 x 5
1 and -5
1 and -5
if you multiply an even number by 5 then it will always end in 0 but if you multiply an odd number by 5 then it will always end in 5.
the reverse would be to divide by 5 or the inverse would be to multiply by 1/5 (both answers are mathematically the same)
F to C: Deduct 32, then multiply by 5, then divide by 9 C to F: Multiply by 9, then divide by 5, then add 32
