Hello I need help what is this I need to show my work 5/8 - 2/6​

Conversion a mixed number 6 2/

7

to a improper fraction: 6 2/7 = 6 2/

7

= 6 · 7 + 2/

7

= 42 + 2/

7

= 44/

7

To find new numerator:

a) Multiply the whole number 6 by the denominator 7. Whole number 6 equally 6 * 7/

7

= 42/

7

b) Add the answer from previous step 42 to the numerator 2. New numerator is 42 + 2 = 44

c) Write a previous answer (new numerator 44) over the denominator 7.

Six and two sevenths is forty-four sevenths

Add: 8/

5

+ 44/

7

= 8 · 7/

5 · 7

+ 44 · 5/

7 · 5

= 56/

35

+ 220/

35

= 56 + 220/

35

= 276/

35

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, 7) = 35. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 7 = 35. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - eight fifths plus forty-four sevenths = two hundred seventy-six thirty-fifths.

Step-by-step explanation:

6x8=48

5x6=30

8x2=16

30/48-16/48= 14/48

Step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

answer: 177/8
