I'm not sure how to do, So it'd be nice if you'd tell me how to do it, and give me the answer so I can do the rest similar to this.

Percent means "per 100" so 1.5% is 1.5 per 100 or (1.5)/100. To get a fraction we want a whole number for both numerator and denominator.

Multiply by 2/2 (another way of multiplying by 1) : (1.5)*2/100(2) equals 3/200.
