Answer:

[tex] \boxed{ \tt{j} = \boxed{\tt 13.5}}[/tex]

Step-by-step explanation:

Given equation:

[tex] \sf \cfrac{j}{ \tt3} = \tt 4.5[/tex]

To find:

Value of x

Solution:

[tex] \implies\sf \cfrac{j}{ \tt3} = \tt 4.5[/tex]

Multiply both sides by 3:

[tex]\sf \implies \cfrac{j}{3} \times 3 = 4.5 \times3[/tex]

Use cancellation method to cancel LHS :

[tex] \sf \implies \cfrac{j}{ \cancel3 \: {}^{1} } \times \cancel3 \: {}^{1} = 4.5 \times 3 \: \: [/tex]

[tex]\sf \implies{j} \times 1 = 4.5 \times 3[/tex]

[tex]\sf \implies{j} = 4.5 \times 3[/tex]

Now Multiply the RHS(4.5 and 3):

[tex] \sf \implies{j} = \boxed{13.5}[/tex]

We're done!

Hence , the value of j would be 13.5 .

[tex] \rule{225pt}{2pt}[/tex]

I hope this helps!
