find the or difference of 6 5/8 - 4=

6 5/8 - 4 = 21

8

= 25

8

= 2.625

Step-by-step explanation:

Conversion a mixed number 6 5

8

to a improper fraction: 6 5/8 = 6 5

8

= 6 · 8 + 5

8

= 48 + 5

8

= 53

8

To find new numerator:

a) Multiply the whole number 6 by the denominator 8. Whole number 6 equally 6 * 8

8

= 48

8

b) Add the answer from previous step 48 to the numerator 5. New numerator is 48 + 5 = 53

c) Write previous answer (new numerator 53) over the denominator 8.

Six and five eighths is fifty-three eighths

Subtract: 53

8

- 4 = 53

8

- 4

= 53

8

- 4 · 8

1 · 8

= 53

8

- 32

8

= 53 - 32

8

= 21

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 1) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 1 = 8. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - fifty-three eighths minus four = twenty-one eighths.
