For about 90% of a star's existence, it fuses hydrogen into helium, producing lots of heat. When the hydrogen starts to become depleted and the helium "ash" starts building up, the star may expand into a red giant, in which it fuses helium into carbon and heavier elements.
Yes, it is true that an average star spends about 90 percent of its life on the main sequence burning hydrogen into helium through nuclear fusion. This is the longest and most stable phase in a star's life cycle before it transitions into the next phase.

90 percent of what?
We normally use only 10 to 20 percent of our minds. Think how different your life would be if you could utilize that other 80 to 90 percent known as the subconscious mind.
"90 percent" means 0.9, and "of" in arithmetic usually means "times". 0.9 x 90 = 81. 90 percent of 90 is 81.
FORTY IS WHAT PERCENT OF 90? FORTY IS WHAT PERCENT OF 90?
Nearly 90 percent of all-stars are in the main-sequence phase of their life cycle. This is when they are fusing hydrogen into helium in their cores, a stable phase that can last for billions of years.
life? I love life!!!!
