Identify multiplication: Identify the multiplication of the two fractions. We have the fraction9j210j2 and we are multiplying it by 15hj. This can be written as (9j210j2)∗(115hj).
Cancel common factors: Cancel out common factors in the numerator and the denominator before multiplying. In this case, we can cancel out the j2 terms.So, (9j210j2)×(115hj) becomes (910)×(115hj) because j2/j2 is 1.
Multiply numerators and denominators: Multiply the numerators and then the denominators. The numerator is 10×15hj, and the denominator is 9×1.So, (910)×(115hj)=9×110×15hj.
Perform multiplication: Perform the multiplication in the numerator and the denominator.The numerator is 10×15hj which is 150hj, and the denominator is 9×1 which is 9.So, (10×15hj)/(9×1)=150hj/9.
Simplify fraction: Simplify the fraction if possible. In this case, we can divide both the numerator and the denominator by 3 to simplify the fraction. 9150hj=(9/3)(150/3)hj=350hj.
