Let a be the amt of perfume A, and b be the amt of perfume B. We have been given that
<span>a+b=3</span> and that <span>a∗15+b∗35=63</span>
From equation 1, we substitute <span>b=3−a</span> so as to get, <span>a∗15+(3−a)∗35=63
</span> which means, <span>15a+105−35a=63</span> which means, <span>−20a=−42
</span><span> so a = 2.1 ounce and b = 0.9 ounce</span>
Kira's fish caught more the first step to find the answer is find the common denominator so Floyds fish weighed 2/3 and Kira's was 7/8 take 8 X 3 = 24 so 24 is the common denominator now you have to take 2 X 8 =16 and 7 X 3 = 21 so Floyds fish is 16/24 and Kira's is 21/24 making Kira's the bigger fish
