6^(-.5) or 6^(-1/2) are both 1/36
Answer:
2:5
Step-by-step explanation:
2*2 = 4
5*2 = 10
Therefore, 2:5 :: 4:10
Step 1: divide numerator (5) by the denominator (9): 5 ÷ 9 = 0.5555555555555556
Step 2: add this value to the the integer part: 3 + 0.5555555555555556 = 3.5555555555555554. So,
3 5/9 = 3.5555555555555554
If you put it into a calculator, you get 35/8 as a fraction and you can change it to a decimal and get 4.375.
Answer:
4 2/7 - 6/7 = 24/
7
= 3 3/
7
Step-by-step explanation:
Conversion a mixed number 4 2/
7
to a improper fraction: 4 2/7 = 4 2/
7
= 4 · 7 + 2/
7
= 28 + 2/
7
= 30/
7
To find a new numerator:
a) Multiply the whole number 4 by the denominator 7. Whole number 4 equally 4 * 7/
7
= 28/
7
b) Add the answer from previous step 28 to the numerator 2. New numerator is 28 + 2 = 30
c) Write a previous answer (new numerator 30) over the denominator 7.
Four and two sevenths is thirty sevenths
Subtract: 30/
7
- 6/
7
= 30 - 6/
7
= 24/
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(7, 7) = 7. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 7 = 49. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - thirty sevenths minus six sevenths = twenty-four sevenths.
