Question

5/ 1/6 = x/0,5

4a-1/a = 2/3 /3

Answer 1

1) 5/1/6 = x/0,5

x/0,5 = ( 5/1 ) × ( 1/6 )

x/0,5 = 5/6

x/(5/10) = 5/6( 5/10 )

x = 25/60 | ÷ 5

x = 5/12

2) 4a - 1/a = 2/3/3

( 4a²/a ) - 1/a = 2/3 ( 1/3 )

4a² - 1 = 2/6

4a² = ( 2/6 ) + 1

4a² = ( 2/6 ) + ( 6/6 )

4a² = 2 + 6

4a² = 8

a² = 8/4

a² = 2

a = √2 → √2 = 1,41
