If you want to add or subtract fractions :

1- make sure that the denominators of the fractions are equal. if they are not, then multiply each of them by a number so that they will be equal.

2- add or subtract the numerators.(if you already had multiplied the denominator of a fraction by a number, then you should multiply the numerator by the same number and do the adding or subtracting)

3- simplify it's possible

here are the answers :

$\frac{3}{7} + \frac{6}{11} = \frac{33 + 42}{77} = \frac{75}{77}$

$\frac{1}{3} + \frac{3}{4} = \frac{4 + 9}{12} = \frac{13}{12} = 1 \frac{1}{12}$

$\frac{4}{5} + \frac{3}{7} = \frac{28 + 15}{35} = \frac{43}{35} = 1 \frac{8}{35}$

$\frac{7}{12} - \frac{1}{8} = \frac{14 - 3}{24} = \frac{11}{24}$

$\frac{9}{10} - \frac{2}{3} = \frac{27 - 20}{30} = \frac{7}{30}$

good luck

Emily tried solving a two step equation for the variable. Interpret whether she made a mistake or not. If she did, describe what

Daniel [21]

-1 = z/3 - 7

Emily's Work:

-1 = z/3 - 7

-1(3)=z/3(3)-7

-3 = z - 7

-3 -7 = z - 7

z = -10

Right away without having to start at the beginning, I see that she has made a mistake at the 4th-5th line of work.

Instead of adding 7 to both sides, she subtracts it and still leaves it in and doesn't fully finish the equation, as it would really be z-7 = -10

In order to solve it, follow these steps:

Rewrite the initial equation as follows:

x/3 - 7 = -1

Multiply both sides by 3
x/3(3)-7(3)=-1(3)

x - 21 = -3

Add 21 to both sides

x = 18
