1 answer:
To change a fraction to a decimal all u do it divide the numerator by the denominator
to change a decimal to a percent you multiple it by 100
to change a percent to a decimal you divide it by 100
and to change a decimal back to a fraction you see what place the last digit of the decimal ends in (maybe tenths, hundredths, or thousandths place) and if it's tenths you put it over 10, if it's hundredths place then put it over 100 and ect.
but if it has whole numbers just write it out and ignore it // ex. 1.25= 1 25/100= 1 1/4
