Question

find the value of an if these are in proportion : (1) 2:8 = 5:n (2) 9 : n = 3:5​

Answer 1

Answer:

1) n = 20

2) n = 15

Step-by-step explanation:

) 2 : 8 = 5 : n

$\frac{2}{8} = \frac{5}{n}$

$2n = 8 \times 5$

$n = \frac{8 \times 5}{2}$

$n = 20$

b) 9 : n = 3 : 5

$\frac{9}{n} = \frac{3}{5}$

$3n = 9 \times 5$

$n = \frac{9 \times 5}{3}$

$n = 15$
