the sum of 1 ⅓ + 2 whole 5/6
Answers
Answer:
1 3/5 - 5/6 = 23
30
≅ 0.7666667
Step-by-step explanation:
Conversion a mixed number 1 3
5
to a improper fraction: 1 3/5 = 1 3
5
= 1 · 5 + 3
5
= 5 + 3
5
= 8
5
To find new numerator:
a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 5
5
= 5
5
b) Add the answer from previous step 5 to the numerator 3. New numerator is 5 + 3 = 8
c) Write previous answer (new numerator 8) over the denominator 5.
One and three fifths is eight fifths
Subtract: 8
5
- 5
6
= 8 · 6
5 · 6
- 5 · 5
6 · 5
= 48
30
- 25
30
= 48 - 25
30
= 23
30
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(5, 6) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 6 = 30. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - eight fifths minus five sixths = twenty-three thirtieths.
