Answer:
Conversion a mixed number 7 1
4
to a improper fraction: 7 1/4 = 7 1
4
= 7 · 4 + 1
4
= 28 + 1
4
= 29
4
To find new numerator:
a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4
4
= 28
4
b) Add the answer from previous step 28 to the numerator 1. New numerator is 28 + 1 = 29
c) Write previous answer (new numerator 29) over the denominator 4.
Seven and one quarter is twenty-nine quarters
Conversion a mixed number 10 1
3
to a improper fraction: 10 1/3 = 10 1
3
= 10 · 3 + 1
3
= 30 + 1
3
= 31
3
To find new numerator:
a) Multiply the whole number 10 by the denominator 3. Whole number 10 equally 10 * 3
3
= 30
3
b) Add the answer from previous step 30 to the numerator 1. New numerator is 30 + 1 = 31
c) Write previous answer (new numerator 31) over the denominator 3.
Ten and one third is thirty-one thirds
Add: 29
4
+ 31
3
= 29 · 3
4 · 3
+ 31 · 4
3 · 4
= 87
12
+ 124
12
= 87 + 124
12
= 211

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(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 cancelling.
In words - twenty-nine quarters plus thirty-one thirds = two hundred eleven twelfths.
Add: the result of step No. 3 + 30 = 211
12
+ 30 = 211
12
+ 30
1
= 211
12
+ 30 · 12
1 · 12
= 211
12
+ 360
12
= 211 + 360
12
= 571

The common denominator you can calculate as the least common multiple of the both denominators - LCM(12, 1) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 1 = 12. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - two hundred eleven twelfths plus thirty = five hundred seventy-one twelfths.
Conversion a mixed number 20 1
2
to a improper fraction: 20 1/2 = 20 1
2
= 20 · 2 + 1
2
= 40 + 1
2
= 41
2
To find new numerator:
a) Multiply the whole number 20 by the denominator 2. Whole number 20 equally 20 * 2
2
= 40
2
b) Add the answer from previous step 40 to the numerator 1. New numerator is 40 + 1 = 41
c) Write previous answer (new numerator 41) over the denominator 2.
Twenty and one half is forty-one halfs
Add: the result of step No. 4 + 41
2
= 571
12
+ 41
2
= 571
12
+ 41 · 6
2 · 6
= 571
12
+ 246
12
= 571 + 246
12
= 817

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(12, 2) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 2 = 24. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - five hundred seventy-one twelfths plus forty-one halfs = eight hundred seventeen twelfths.
