Answer:
(b:10):9=17 rest 6
b:10=17×9+ 6
b:10=153+6
b=159×10
b=1590
(240:10x37):d=7 rest 6
24x37=7d+ 6
888=7d+6
7d=882
d=126
Step-by-step explanation:
Plain : Spotted : Striped socks are in the ratio of 5 : 3 : 8
So we can say that number of plain socks = 5x
Number of spotted socks = 3x
Number of striped socks = 8x
Hence, total number of socks = 5x + 3x + 8x = 16x
⇒ Fraction of Striped Socks = 
⇒ Fraction of Striped Socks = 
⇒ Fraction of Striped Socks = 
Hence, of Alex's socks are striped
The answer is: [C]: "30%" .

Explanation:
_____________________________________________________
Note that: "%" ; or "percent" means "out of 100" ; or "divided by 100" .
______________________________________________________
Method 1)
15/50 = ?/ 100 ;
Look at the denominators:
50 * (what value?) = 100 ? ; → "100 ÷ 50 = 2" ;
→ 50 * 2 = 100 ;
So: "15/50 = (15*2)/(50*2) = "30/100" ; which is "30%" .
___________________________________________
Method 2:
___________________________________________
"15/50" = (15÷5) / (50÷5) = 3/10 ;
3/10 = (3*10) / (10*10) = 30/100 ; which is: "30%" .
__________________________________________
Method 3: (slight variation of "Method 2" above):
___________________________________________
"15/50" = (15÷5) / (50÷5) = 3/10 ;
3/10 = 0.3 = 0.30 = (0.30 * 100) % = " 30% " .
