in converting fractions to percent rates. we must rename it to decimal first
1.
=(1÷1) + (2÷7)
=1+0.2857
=1.2857
2. now we can rename it into percent. in converting decimal to percent we simply have to multiply it by 100.
=1.2857 x 100
=128.57%

get a Texas Instruments model 36 calculator. It does the conversion but isn't as crazy as the 83 model. I'd help with a real answer but mine is at home.
