Answer 1

Answer:

13/(1 3/7)*1 = $9.10

Step-by-step explanation:

Simplify the following:

13/(1 + 3/7)

Hint: | Put the fractions in 1 + 3/7 over a common denominator.

Put 1 + 3/7 over the common denominator 7. 1 + 3/7 = 7/7 + 3/7:

13/(7/7 + 3/7)

Hint: | Add the fractions over a common denominator to a single fraction.

7/7 + 3/7 = (7 + 3)/7:

13/((7 + 3)/7)

Hint: | Evaluate 7 + 3.

7 + 3 = 10:

13/(10/7)

Hint: | Write 13/(10/7) as a single fraction.

Multiply the numerator of 13/(10/7) by the reciprocal of the denominator. 13/(10/7) = (13×7)/10:

(13×7)/10

Hint: | Multiply 13 and 7 together.

13×7 = 91:

Answer:  91/10 or 9.10 decimal
