5比8少3，3是8的3/8*100%=37.5%，即5比8少百分之37.5。
具体计算如下：
（8-5）÷8×100%
=3÷5×100% =3÷8×100%
=0.6×100% =0.375×100%
=60% =37.5%
扩展资料：
百分数是分母为100的特殊分数，其分子可不为整数。百分数表示一个数是另一个数的百分之几，表示一个比值。百分比是一种表达比例、比率或分数数值的方法，如82%代表百分之八十二，或82/100、0.82。
百分比是一种表达比例，比率或分数数值的方法，如82%代表百分之八十二，或82/100、0.82。成和折则表示十分之几，举例如“七成”和“七折”，代表70/100或70%或0.7。所以百分比后面不能接单位。
