just multiply the percentage with the number you have

$1)\left(\frac{92.5}{100}\right)(550)$ you calculate it

$3)\left(\frac{22}{100}\right)(1098)+1098$ you calculate it

$2)\frac{464}{16(2.32)}$ multiply the denominator and the numerator with 100

$\frac{464(100)}{16(100\times 2.32)}$

$\frac{46400}{16(232)}$ take factor 2 from 464

$\frac{2(23200)}{16(232)}$

$\frac{2(100)}{16}$ you can continue
