Answer:

Add: 1/

2

+ 1/

5

= 1 · 5/

2 · 5

+ 1 · 2/

5 · 2

= 5/

10

+ 2/

10

= 5 + 2/

10

= 7/

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(2, 5) = 10. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 5 = 10. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - one half plus one fifth = seven tenths.

Add: the result of step No. 1 + 4/

5

= 7/

10

+ 4/

5

= 7/

10

+ 4 · 2/

5 · 2

= 7/

10

+ 8/

10

= 7 + 8/

10

= 15/

10

= 5 · 3/

5 · 2

= 3/

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(10, 5) = 10. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 5 = 50. In the following intermediate step, cancel by a common factor of 5 gives 3/

2

.

In other words - seven tenths plus four fifths = three halfs.

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 a 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

Add: the result of step No. 2 + 5/

3

= 3/

2

+ 5/

3

= 3 · 3/

2 · 3

+ 5 · 2/

3 · 2

= 9/

6

+ 10/

6

= 9 + 10/

6

= 19/

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(2, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 3 = 6. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - three halfs plus five thirds = nineteen sixths.
