how do you write 1 over 50 as a decimal
Report Abuse. Multiply the numerator and the denominator with 1/50 with 2 then you will get 2/100. the rule is if you multiply numerator and denominator with same number the value does not change.2/100 we can written 0.02 as the blind rule we have keep the decimal after two places because in 100 two zeroes are there. OK.eport Abuse. anytime you want to change a fraction into a decimal, you divide the numerator (top number) by the denominator (bottom). so, here it's 1 divided by 50 which is 0.02.
