Answer:
j = 9
Step-by-step explanation:
The answer to the question above is solved below.
[tex]1 \frac{2}{3}j = 15[/tex]
Convert the mixed numbers to improper fraction following the step: 1×3 = 3 +2 =5 / 3j = 5/3j
[tex] \frac{5}{3}j = 15[/tex]
Eliminate the fraction of the equation left hand side by multiplying both sides by 3
[tex]3 \times \frac{5}{3}j = 3 \times 15[/tex]
[tex]5j = 45[/tex]
Divide both sides by 5
[tex] \frac{5j}{5} = \frac{45}{5} [/tex]
[tex]j = 9[/tex]
[tex]thus \: if \: 1 \frac{2}{3}j = 15. \: j = 9[/tex]
