How to solve 1 2/3j=15

ivann1987 [24]

Answer:

j = 9

Step-by-step explanation:

The answer to the question above is solved below.

$1 \frac{2}{3}j = 15$

Convert the mixed numbers to improper fraction following the step: 1×3 = 3 +2 =5 / 3j = 5/3j

$\frac{5}{3}j = 15$

Eliminate the fraction of the equation left hand side by multiplying both sides by 3

$3 \times \frac{5}{3}j = 3 \times 15$

$5j = 45$

Divide both sides by 5

$\frac{5j}{5} = \frac{45}{5}$

$j = 9$

$thus \: if \: 1 \frac{2}{3}j = 15. \: j = 9$
