<em>60 ; 100</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>HCF = 20 = 4×5 = 2²×5</em>
<em>LCM = 300 = 3×100 = 3×4×25 = 2²×3×5²</em>
<em>LCM/HCF = 2²×3×5²/2²×5 = 3×5</em>
<em>a = 3×hcf = 3×20 = 60</em>
<em>b = 5×lcm = 5×20 = 100</em>
<em>Good luck !</em>

Answer:
56%
Step-by-step explanation:
14/25*4/4=56/100=56%
(-y+5x3)+(7.2y-9)=6.2y+n
(-y+15)+(7.2y-9)=6.2y+n
since you're adding the two parentheses, you don't need to have them there
-y+15+7.2y-9=6.2y+n
7.2y-y +15-9 =6.2y+n
6.2y + 6 =6.2y+n
6.2y - 6.2y -n = -6
-n=-6
n=6
