hello! i cant understand this problem, please help me?

When you write a percent as a decimal, all you do is move the decimal point two spots back. So 75% is .75. 43% is .43. 22% is .22. Now, for 50%, the decimal point is behind the zero, so 50% as a fraction would be .5 5% as a decimal would be .05.

Now, you try to express 35% as a decimal
