Answer:

Box 5= 9

Explanation:

Step1: convert 1 4/5 to a fraction. 9/5

9/5÷2/7

Step2: use the KCF method (keep, change, flip) you'll keep the 9/5 then you'll change the ÷ to x, then you will flip the 2/7 to7/2

9/5 x 7/2= 63/10

Answer: 1 4/5 / 2/7 = 63/

10

= 6 3/10

= 6.3

Explanation:

Conversion a mixed number 1 4/

5

to a improper fraction: 1 4/5 = 1 4/

5

= 1 · 5 + 4/

5

= 5 + 4/

5

= 9/

5

To find a new numerator:

a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 5/

5

= 5/

5

b) Add the answer from previous step 5 to the numerator 4. New numerator is 5 + 4 = 9

c) Write a previous answer (new numerator 9) over the denominator 5.

One and four fifths is nine fifths

Divide: 9/

5

: 2/

7

= 9/

5

· 7/

2

= 9 · 7/

5 · 2

= 63/

10

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/

7

is 7/

2

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, the fraction result cannot be further simplified by canceling.

In other words - nine fifths divided by two sevenths = sixty-three tenths.
