Sam drove 6 1/2 hours on Saturday and 8 2/3 hours on Sunday. How much longer was his drive on Sunday than on Saturday?

Schach [20]

Based on the phrase "how much longer" this is going to be a subtraction problem
8 2/3 - 6 1/2
Steps:
1. Find the least common denominator. Both 3 and 2 have a multiple of 6
2. Multiply 2/3 by 2 (numerator and denominator) and 1/2 by 3 to get an overall denominator of 6
8 4/6 - 6 3/6
3. Now you can do basic subtraction. Subtract the whole numbers
8-6= 2
4. subtract the numerators
4-3=1
Answer is 2 1/6

H/j=15 solve for j <br> Please answer

Katyanochek1 [597]

Hey!

Let's write the problem,
$\frac{H}{j}=15$
Multiply both sides by $j$ in order to undo the fraction.
$\frac{H}{j}j=15j$
$H=15j$
Let's switch sides so that we end up with $j$ on the left side.
$15j=H$
Divide both sides by $15$ .
$\frac{15j}{15}=\frac{H}{15}$

Our final answer would be,
$j=\frac{H}{15}$

Thanks!
