Question

Can someone help me solve this proportion: 5/n=1.5/1.8

Answer 1

$\frac{5}{n} =\frac{1.5}{1.8} \\ \\ n\neq 0 \\ \\1.5n=5\cdot 1.8\\ \\1.5n= 9 \ \ / : 1.5 \\ \\ n=6$

Answer 2

5/n = 1.5/1.8 Multiply each side by 'n': 5= 1.5n/1.8 Multiply each side by 1.8 : 9 = 1.5n Divide each side by 1.5 : 6 = n =====<=======<== Easier: 5/n = 1.5/1.8 Perform the division on the right side: 5/n = 5/6 Multiply each side by 'n' : 5 = 5n/6 Multiply each side by 6 : 30 = 5n Divide each side by 5 : 6 = n
