740, 89-5%

$${\mathtt{740.89}}{\mathtt{\,-\,}}{\mathtt{5}}\% = {\mathtt{703.845\: \!5}}$$

100% - 5% = 95%

$${\frac{{\mathtt{740.89}}{\mathtt{\,\times\,}}{\mathtt{95}}}{{\mathtt{100}}}} = {\mathtt{703.845\: \!5}}$$            ;     $${\mathtt{740.89}}{\mathtt{\,\times\,}}{\mathtt{95}}\% = {\mathtt{703.845\: \!5}}$$
