Question

Ike notices an interesting pattern; he sees that 7 is 14% of a and 18 is 6% of b. If c is b/a, then what is the value of c? ​

Answer 1

Answer: c = 6

Step-by-step explanation:

%/100 = is/of

14/100 = 7/a. (14% of what number is 7) (cross multiplication)

(7*100)/14 = 50 (a)

6/100 = 18/b

(18*100)/6 = 300 (b)

b/a = 300/50 = 6

Answer 2

Pattern is a rule that guides the formation of a dataset. Based on the given patterns of a and b, the value of c is 6

Given that:

$7 = 14\% \times a$

$18 = 6\% \times b$

Make a the subject in $7 = 14\% \times a$

$a=7 \div 14\%$

$a = 50$

Make b the subject in $18 = 6\% \times b$

$b = 18 \div 6\%$

$b = 300$

Given that:

$c = \frac ba$

Substitute values for a and b

$c = \frac{300}{50}$

$c = 6$

Hence, the value of c is 6
