Write 6.4% as a decimal and as a fraction.
Write 2 and one fourth as a decimal and as a percent.
To convert from percent to decimal simpoy divide by 100.
6.4% = 0.064.
To convert to fraction (do you want a mixed fraction or not? and percent or not?). For a mixed fraction you read 6.4% and write 64/10% which reduces to 62/5%. If you want to convert that to a fraction ( not mixed between fraction and a whole number) just multiply (5 x 6) + 2 = 32/5%. If you don't want the percent sign on the fraction, go back to the decimal (0.064) and that becomes 64/1000 which reduces to 32/500 or 16/250 or 8/125.
