Perform the operation(s) and write the answer in simplest form. 7 5/9-3 7/9

First do 12-5, which equals 7. Next, subtract 1/10 from 2/5. 2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2. 4/10-1/10=3/10. Now add 7 and 3/10. You will get 7 3/10 as the answer, which is letter C.)

(12+13)/154

25/154 is the answer to the question

the answer is not listed in the above choices

3/7+5/14

6/14+5/14

11/14

11/14 is already in the simplest form.

Hope it helps.

[tex]7\dfrac{5}{9}-3\dfrac{7}{9}=6\dfrac{9+5}{9}-3\dfrac{7}{9}=6\dfrac{14}{9}-3\dfrac{7}{9}=(6-3)+\dfrac{14-7}{9}=3\dfrac{7}{9}[/tex]

The answer is A.) 9 2/7. You just add the full numbers and then the fraction is added to the sum.

0.162

Step-by-step explanation:

(12+13)/154

25/154

0.162

The answer is C. 5 13/20

In order to add fractions, both fractions must have the same denominator.

A denominator is the lower number of a fraction.

In the fraction [tex]\frac{3}{7}[/tex], the denominator is 7.

In the fraction [tex]\frac{3}{7}[/tex], the denominator is 14.

Since 7 ≠ 14, you must find the LCM (least common multiple) of 7 and 14.

To do this, list the multiples of 7 and 14 separately until you find one that both numbers share.

7 • 1 = 7

7 • 2 = 14

14 • 1 = 14

The LCM of 7 and 14 is 14.

This means that the common denominator that these fractions will be converted to fit will be 14.

Since 7 • 2 = 14, which is what the denominator needs to be, you must also multiply the numerator, or upper number of the fraction, by 2.

3 • 2 = 6

[tex]\frac{3}{7}[/tex] = [tex]\frac{6}{14}[/tex]

[tex]\frac{6}{14}[/tex] and [tex]\frac{5}{14}[/tex] now have common denominators and you can add them together!

To add fractions with common denominators, simply add the numerators and the denominator stays the same.

[tex]\frac{6}{14}[/tex] + [tex]\frac{5}{14}[/tex] = [tex]\frac{6 + 5}{14}[/tex]

6 + 5 = 11

[tex]\frac{11}{14}[/tex] is sum of [tex]\frac{6}{14}[/tex], which is an equivalent fraction to [tex]\frac{3}{7}[/tex], and [tex]\frac{5}{14}[/tex].

Hope this helps!

First add the fractions in the parenthesis: 1/2+1/3.. In order to do this find the common denominator, which in this case is 6. So 3/6+2/6=5/6. Now you have 5/6/15/4. Divide the fractions and then simplify to get 2/9.

Hope the explanation helped!
