What is, 7 3/10+6 1/3+2 7/10?

Answers

Answer 1

Answer:

7 3/10 + 6 1/3 + 2 7/10

First change them to improper fractions

73/10 + 19/3 + 27/10

now find the common denominator which would be 30

73/10 = 219 /30

19/3 = 190/30

27/10 = 81 /30

now add (219 + 190 + 81) = 490/30

now divide 490 ÷ 30 = 16 1/3

Your answer is 16 1/3

Hope this helps. :)

Answer 2

Answer: We are going to add 7 3/10 and 2 7/10 first. $\boxed{\boxed{7 (3)/(10)}}+\boxed{\boxed{2 (7)/(10)}}}=\boxed{\boxed{9 (10)/(10)}}$ . Now we are going to add $\boxed{\boxed{9{ (10)/(10)}}}$ by $\boxed{\boxed{6{ (1)/(3)}}}$ . $\boxed{\boxed{9{ (10*3)/(10*3)}}}=\boxed{\boxed{9{ (30)/(30)}}} \ and \ \boxed{\boxed{6 (1*10)/(3*10)}}}=\boxed{\boxed{6{ (10)/(30)}}}$ . Finnally we add. $\boxed{\boxed{9{ (30)/(30)}}}+{\boxed{\boxed{6{ (10)/(30)}}}=\boxed{\boxed{15 (40)/(30)}}}.$ . Last, but not least we simplify, $\boxed{\boxed{15{ (30:10)/(40:10)}}}=\boxed{\boxed{15 (3)/(4)}}}$ . Therefore, your answer is $\boxed{\boxed{15 (3)/(4)}}}$ . Hoped I helped. :)

Step-by-step explanation:

Gina charges $28 for 3 hours of swimming lessons. Hector charges $18 for 2 hurs of swimming lessons. Which instructor offers a better deal?

Answers

Answer:

Hector offers a better deal: $18 for 2 hours.

Step-by-step explanation:

1. You have the following information given in the problem above:

- Ginas offers $28 for 3 hours.

- Hector offers: $18 for 2 hours.

2. Then, you must write the rates:

a) $28 for 3 hours:

$(28)/(3)=9.33$ dollars per hour.

b) $18 for 2 hours:

$(18)/(2)=9$ dollars per hour.

3. Therefore, the better deal is $18 for 2 hours

Answer:

Hector is providing best deal.

Step-by-step explanation:

Given data:

Gina charges = $28

Time by Gina = 3 hours

Hector charges = $18

Time by Hector = 2 hours

Solution:

Charges per hour by Gina = $28/3

= $9.33

Charges per hours by hector = $18/2

= $9

Hence hector charges low per hour than Gina. So hector provides the best deal.

Explanation:

Now the both instructor provides lesson with different charges with different hour. So if we calculate the charges per hour than the charges per hour Gina is charging more than hector.

Hector is charging $9 for one hour and $27 for 3 hour while Gina is charging $28 for 3 hours.

So the Hector is providing best deal.
