$\frac{(-3}{6)+}$ $\frac{(-4}{7)}$ = Answer: $\frac{15}{-14}$

SOLUTION 1 :

Remember:

To add numbers with the same sign, add their absolute values. The sum will have the same sign as the numbers being added.

Solve:

You are adding two numbers with the same sign, so add their absolute values:

$\frac{-3}{6}$ + $\frac{-4}{7}$

= $\frac{(-24}{42)}$ + $\frac{(-21}{42)}$

= $\frac{-45}{42}$

= $\frac{15}{-14}$

Since the numbers being added are negative, the result must also be negative:

$\frac{15}{-14}$ → $\frac{15}{-14}$

So , ( $\frac{-3}{6}$ ) + $\frac{(-4}{7)}$ = $\frac{15}{-14}$

Subtract.

$\frac{6}{7}$ - $\frac{3}{7}$ = Answer: $\frac{3}{7}$

SOLUTION 1 :

Remember:

To add numbers with different signs, subtract the lesser absolute value from the greater absolute value. The sum will have the same sign as the number with the greater absolute value.

Solve:

Subtract:

$\frac{6}{7}$ - $\frac{3}{7}$

= $\frac{3}{7}$

Since you are subtracting a smaller number from a larger number, the result must be positive.

So , $\frac{6}{7}$ - $\frac{3}{7}$ = $\frac{3}{7}$

Add.

$\frac{3}{4}$ + $\frac{(-8}{5)}$ = Answer: $\frac{-17}{20}$

SOLUTION 1 :

Remember:

To add numbers with different signs, subtract the lesser absolute value from the greater absolute value. The sum will have the same sign as the number with the greater absolute value.

Solve:

You are adding two numbers with different signs, so subtract the lesser absolute value from the greater absolute value:

$\frac{3}{4}$ + $\frac{(-8}{5)}$

= $\frac{(-32}{20)}$ - $\frac{15}{20}$

= $\frac{-17}{20}$

Since the number with the greater absolute value is negative, the result must also be negative:

$\frac{-17}{20}$ → $\frac{-17}{20}$

So , $\frac{3}{4}$ + $\frac{(-8}{5)}$ = $\frac{-17}{20}$

Add.

$\frac{(-2}{4)+}$ $\frac{(-3}{7)}$ = Answer: $\frac{-13}{14}$

SOLUTION 1 :

Remember:

To add numbers with the same sign, add their absolute values. The sum will have the same sign as the numbers being added.

Solve:

You are adding two numbers with the same sign, so add their absolute values:

$\frac{-2}{4}$ + $\frac{-3}{7}$

= $\frac{(-12}{28)}$ + $\frac{(-14}{28)}$

= $\frac{-26}{28}$

= $\frac{-13}{14}$

Since the numbers being added are negative, the result must also be negative:

$\frac{-13}{14}$ → $\frac{-13}{14}$

So , ( $\frac{-2}{4}$ ) + $\frac{(-3}{7)}$ = $\frac{-13}{14}$

Subtract.

$\frac{2}{6}$ + $\frac{(-8}{5)}$ = Answer: $\frac{19}{-15}$

SOLUTION 1 :

Remember:

To add numbers with different signs, subtract the lesser absolute value from the greater absolute value. The sum will have the same sign as the number with the greater absolute value.

Solve:

You are adding two numbers with different signs, so subtract the lesser absolute value from the greater absolute value:

$\frac{2}{6}$ + $\frac{(-8}{5)}$

= $\frac{(-48}{30)}$ - $\frac{10}{30}$

= $\frac{-38}{30}$

= $\frac{19}{-15}$

Since the number with the greater absolute value is negative, the result must also be negative:

$\frac{19}{-15}$ → $\frac{19}{-15}$

So , $\frac{2}{6}$ + $\frac{(-8}{5)}$ = $\frac{19}{-15}$

Solve:

You are adding two numbers with the same sign, so add their absolute values:

$\frac{-2}{4}$ + $\frac{-4}{7}$

= $\frac{-30}{28}$

= $\frac{15}{-14}$

Since the numbers being added are negative, the result must also be negative:

$\frac{15}{-14}$ → $\frac{15}{-14}$

So , ( $\frac{-2}{4}$ ) + $\frac{(-4}{7)}$ = $\frac{15}{-14}$

$\frac{1}{4}$ + $\frac{(-6}{5)}$ = Answer: $\frac{-19}{20}$

SOLUTION 1 :

Remember:

To add numbers with different signs, subtract the lesser absolute value from the greater absolute value. The sum will have the same sign as the number with the greater absolute value.

Solve:

You are adding two numbers with different signs, so subtract the lesser absolute value from the greater absolute value:

$\frac{1}{4}$ + $\frac{(-6}{5)}$

= $\frac{(-24}{20)}$ - $\frac{5}{20}$

= $\frac{-19}{20}$

Since the number with the greater absolute value is negative, the result must also be negative:

$\frac{-19}{20}$ → $\frac{-19}{20}$

So , $\frac{1}{4}$ + $\frac{(-6}{5)}$ = $\frac{-19}{20}$

$\frac{(-2}{6)+}$ $\frac{(-4}{7)}$ = Answer: $\frac{19}{-21}$

SOLUTION 1 :

Remember:

To add numbers with the same sign, add their absolute values. The sum will have the same sign as the numbers being added.

Solve:

You are adding two numbers with the same sign, so add their absolute values:

$\frac{-2}{6}$ + $\frac{-4}{7}$

= $\frac{(-24}{42)}$ + $\frac{(-14}{42)}$

= $\frac{-38}{42}$

= $\frac{19}{-21}$

Since the numbers being added are negative, the result must also be negative:

$\frac{19}{-21}$ → $\frac{19}{-21}$

So , ( $\frac{-2}{6}$ ) + $\frac{(-4}{7)}$ = $\frac{19}{-21}$
