Answer:

  13/4 = 3 1/4

Step-by-step explanation:

You can convert each improper fraction to a mixed number, or vice versa to answer this.

I started by looking at the fractions with 4 in the denominator, since there are two mixed numbers with 4 in the denominator. Below we show the conversions of all of the mixed numbers.

To convert a mixed number to an improper fraction, multiply the integer by the denominator and add the numerator. Express the total over the denominator:

  k+(n)/(d)=(kd+n)/(d)

So, you have ...

  • 1 3/4 = (4+3)/4 = 7/4
  • 5 1/6 = (5·6 +1)/6 = 31/6
  • 3 2/5 = (3·5 +2)/6 = 17/5
  • 3 1/4 = (3·4 +1)/4 = 13/4 . . . . matches the first improper fraction

The appropriate choice is ...

  13/4 = 3 1/4

_____

You can also convert the improper fractions to mixed numbers. Divide the numerator by the denominator. The result is an integer and a remainder. The remainder is expressed over the divisor as a fraction:

  • 13/4 = 3 remainder 1 = 3 1/4 . . . . matches the last mixed number
  • 16/5 = 3 remainder 1 = 3 1/5
  • 31/4 = 7 remainder 3 = 7 3/4
  • 17/6 = 2 remainder 5 = 2 5/6

6/9=c/6 what does c equal?

Answers

\frac { 6 }{ 9 } =\frac { c }{ 6 } \n \n \frac { 2 }{ 3 } =\frac { c }{ 6 } \n \n 6\cdot \frac { 2 }{ 3 } =\frac { c }{ 6 } \cdot 6

\n \n c=\frac { 12 }{ 3 } \n \n \therefore \quad c=4
C=4         because 4/6 is equivalent to 6/9 and they would reduce down to 2/3
