Answer:
17 3/2 - 5 100/8 = 1/1 = 1
Step-by-step explanation:Conversion a mixed number 17 3/
2
to a improper fraction: 17 3/2 = 17 3/
2
= 17 · 2 + 3/
2
= 34 + 3/
2
= 37/
2
To find a new numerator:
a) Multiply the whole number 17 by the denominator 2. Whole number 17 equally 17 * 2/
2
= 34/
2
b) Add the answer from previous step 34 to the numerator 3. New numerator is 34 + 3 = 37
c) Write a previous answer (new numerator 37) over the denominator 2.
Seventeen and three halfs is thirty-seven halfs
Conversion a mixed number 5 100/
8
to a improper fraction: 5 100/8 = 5 100/
8
= 5 · 8 + 100/
8
= 40 + 100/
8
= 140/
8
To find a new numerator:
a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8/
8
= 40/
8
b) Add the answer from previous step 40 to the numerator 100. New numerator is 40 + 100 = 140
c) Write a previous answer (new numerator 140) over the denominator 8.
Five and one hundred eighths is one hundred forty eighths
Subtract: 37/
2
- 140/
8
= 37 · 4/
2 · 4
- 140/
8
= 148/
8
- 140/
8
= 148 - 140/
8
= 8/
8
= 8 · 1/
8 · 1
= 1
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, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 8 = 16. In the following intermediate step, cancel by a common factor of 8 gives 1/
