For homework i have to find out how many watts of electricity we use compared to how much we could if using a CFL light bulb and i need to find out how many watts are used compared to a 60 watt regular bulb. i know 100 is equal to 26. so what is 60 equal to?
The ratio is around one quarter, so the answer is 15 watts.
How do you compare watts in a CFL light bulb?

The ratio is around one quarter, so the answer is 15 watts.

Do the ratio
100 : 26 = 60 : X
Or go to the market and look at the lamps in their packages.
The Watts and ‘equivalent’ ratings are listed.
The measure of light actually emitted is in ‘Lumens”, and you will
find that the ‘equivalent’ ratings are only close, not exact.

i dont understand your question
you want to compare the efficiency
a CFL and an incandescent bulb of same wattage consume same power but their light output measured in lumens will be higher in a CFL than an incandescent one
for efficiency calculation find the rower consumed per lumens for both the types you do that by dividing the wattage rating by the lumens and compare both
you can also do the other way by finding the lumens per watt and comparing them
