Question

Can someone please teach me how to solve question 1 and 2

Answer 1

see explanation

Explanation:

One way is to use the method of cross- multiplication, that is

Given

`(a)/(b)` =
`(c)/(d)`, then

ad = bc

(1)

Given

`(1)/(4\\)` =
`(6)/(n\\)` ( cross- multiply )

n = 4 × 6 = 24

(2)

Given

`(2)/(6\\)` =
`(n)/(36)` ( cross- multiply )

6n = 72 ( divide both sides by 6 )

n = 12

Answer 2

1•n = 4•6 (multiply)
1•n = 24 (divide 24/1)
n= 24

2•36=6•n
72=6•n
72/6=12
n=12
