2 1/3 divided by 1/4
zloy xaker [14]
Answer:

28/3

Step-by-step explanation:

2 1/3 divided by 1/4

We’ll start by 2 1/3

Multiply 3 x 2 and then add 1

3 x 2 = 6 + 1 = 7

Then add the denominator back

7/3

Now divide 7/3 by 1/4 like this!

Start by multiplying 4 by 7

4 x 7 = 28

Then multiply 3 by 1

3 x 1 = 3

Final results: 28/3

Samantha’s college runs on a trimester schedule so she receives a bill 3 times a year for tuition. Each trimester costs $1,450,
SOVA2 [1]

Answer:

The total cost of Samantha's college degree is approximately $10,800.

Step-by-step explanation:

Cost of each trimester = $1,450

Now, total cost of fees per year = 3 x Cost of each trimester

= 3 x $1,450 = $4350

So, cost of fees in 2 complete years = 2 x $4,350 = $8,700

Also, Cost of books each trimester =$350

Now, total cost of books per year = 3 x Cost of each trimester

= 3 x $350 = $1,050

So, cost of books in 2 complete years = 2 x $1,050 = $2,100

So, total cost  of Samantha's college = Total Trimester fees cost +Total books cost

= $8,700 + $2,100 = $10,800

Hence, the total cost of Samantha's college is approximately $10,800.
