Answer:

6 5/4 - 1 2/3 = 67/12 = 5 7/12 = 5.5833333

Step-by-step explanation:

Conversion a mixed number 6 5/

4

to a improper fraction: 6 5/4 = 6 5/

4

= 6 · 4 + 5/

4

= 24 + 5/

4

= 29/

4

To find new numerator:

a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/

4

= 24/

4

b) Add the answer from previous step 24 to the numerator 5. New numerator is 24 + 5 = 29

c) Write a previous answer (new numerator 29) over the denominator 4.

Six and five quarters is twenty-nine quarters

Conversion a mixed number 1 2/

3

to a improper fraction: 1 2/3 = 1 2/

3

= 1 · 3 + 2/

3

= 3 + 2/

3

= 5/

3

To find new numerator:

a) Multiply the whole number 1 by the denominator 3. Whole number 1 equally 1 * 3/

3

= 3/

3

b) Add the answer from previous step 3 to the numerator 2. New numerator is 3 + 2 = 5

c) Write a previous answer (new numerator 5) over the denominator 3.

One and two thirds is five thirds

Subtract: 29/

4

- 5/

3

= 29 · 3/

4 · 3

- 5 · 4/

3 · 4

= 87/

12

- 20/

12

= 87 - 20/

12

= 67/

12

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 both denominators - LCM(4, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 3 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - twenty-nine quarters minus five thirds = sixty-seven twelfths.

Yan na po lahat po alam ko po :)

Answer:

5 7/12

Step-by-step explanation:

5. 6 5/4 - 1 2/3 =

4×6+5=29 3×1+2=5

=29/4 =5/3

12 ÷ 4 × 29 - 12 ÷ 3 × 5

12 12

= 87/12 - 20/12

= 67/12

67 ÷ 12 = 5 7/12
