Step-by-step explanation: To add and subtract fractions with the same denominator, or bottom number, place the 2 fractions side by side. Add or subtract the numerators, or the top numbers, and write the result in a new fraction on the top. The bottom number of the answer will be the same as the denominator of the original fractions.
<h2><em>James has $9
</em></h2><h2><em>Priya has $10.80
</em></h2><h2><em>Siobhan has $9.18
</em></h2><h2><em>because 9*20% is 1.8 so add that to 9 to get 10.80 then times 10.80 by 15% to get 1.62 so you subtract 1.62 from 10.80 to get $9.18 </em></h2>
