Answer: 3. 6.75
4. 3.16666666667
5. -3.61904761905
Step-by-step explanation:1.Conversion a mixed number 4 1/
3
to a improper fraction: 4 1/3 = 4 1/
3
= 4 · 3 + 1/
3
= 12 + 1/
3
= 13/
3
To find new numerator:
a) Multiply the whole number 4 by the denominator 3. Whole number 4 equally 4 * 3/
3
= 12/
3
b) Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13
c) Write a previous answer (new numerator 13) over the denominator 3.
Four and one third is thirteen thirds
Subtract: 5/
7
- 13/
3
= 5 · 3/
7 · 3
- 13 · 7/
3 · 7
= 15/
21
- 91/
21
= 15 - 91/
21
= -76/
21
2.Conversion a mixed number 3 2/
3
to a improper fraction: 3 2/3 = 3 2/
3
= 3 · 3 + 2/
3
= 9 + 2/
3
= 11/
3
To find new numerator:
a) Multiply the whole number 3 by the denominator 3. Whole number 3 equally 3 * 3/
3
= 9/
3
b) Add the answer from previous step 9 to the numerator 2. New numerator is 9 + 2 = 11
c) Write a previous answer (new numerator 11) over the denominator 3.
Three and two thirds is eleven thirds
Subtract: 11/
3
- 1/
2
= 11 · 2/
3 · 2
- 1 · 3/
2 · 3
= 22/
6
- 3/
6
= 22 - 3/
6
= 19/
6
3.
Conversion a mixed number 6 3/
3
to a improper fraction: 6 3/3 = 6 3/
3
= 6 · 3 + 3/
3
= 18 + 3/
3
= 21/
3
To find new numerator:
a) Multiply the whole number 6 by the denominator 3. Whole number 6 equally 6 * 3/
3
= 18/
3
b) Add the answer from previous step 18 to the numerator 3. New numerator is 18 + 3 = 21
c) Write a previous answer (new numerator 21) over the denominator 3.
Six and three thirds is twenty-one thirds
Subtract: 21/
3
- 1/
4
= 21 · 4/
3 · 4
- 1 · 3/
4 · 3
= 84/
12
- 3/
12
= 84 - 3/
12
= 81/
12
= 3 · 27/
3 · 4
= 27/
