8 $\frac{3}{7}$ + 6 $\frac{2}{7}$

(use / ) Answer: 14 Answer: $\frac{5}{7}$

SOLUTION 1 :

Add:

8 $\frac{3}{7}$ + 6 $\frac{2}{7}$

= 14 $\frac{5}{7}$

Since the numbers being added are positive, the result must also be positive.

8 $\frac{3}{7}$ + 6 $\frac{2}{7}$ = 14 $\frac{5}{7}$

Add. Write your answer as a decimal.

$\frac{2}{7}$ + 9.5

Answer: 9.79

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:

First, rewrite the fraction as a decimal:

$\frac{2}{7}$ + 9.5

0.29 + 9.5

Add:

0.29 + 9.5 = 9.79

$\frac{2}{7}$ + 9.5 = 9.79

Add. Write your answer as a decimal.

7.5 + -1.4 = Answer: 6.1

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:

7.5 -1.4 = 6.1

Since the number with the greater absolute value is positive, the result must also be positive.

So:

7.5 + -1.4 = 6.1

Add. Simplify your answer and write it as a proper fraction or as a whole or mixed number.

$\frac{4}{5}$ + $\frac{1}{11}$

(use / ) Answer: $\frac{5}{16}$

SOLUTION 1 :

Add:

$\frac{4}{5}$ + $\frac{1}{11}$

= $\frac{5}{16}$

Since the numbers being added are positive, the result must also be positive.

$\frac{4}{5}$ + $\frac{1}{11}$ = $\frac{5}{16}$

Add. Write your answer as a decimal.

3.3 + $\frac{4}{7}$

Answer: 3.87

SOLUTION 1 :

First, rewrite the fraction as a decimal:

3.3 + $\frac{4}{7}$

3.3 + 0.57

Add:

3.3 + 0.57 = 3.87

Since the numbers being added are positive, the result must also be positive.

3.3 + $\frac{4}{7}$ = 3.87

Add. Simplify your answer and write it as a proper fraction or as a whole or mixed number.

4 $\frac{3}{7}$ + 5 $\frac{2}{7}$

(use / ) Answer: 9 Answer: $\frac{5}{7}$

SOLUTION 1 :

Add:

4 $\frac{3}{7}$ + 5 $\frac{2}{7}$

= 9 $\frac{5}{7}$

Since the numbers being added are positive, the result must also be positive.

4 $\frac{3}{7}$ + 5 $\frac{2}{7}$ = 9 $\frac{5}{7}$

Add. Write your answer as a decimal.

$\frac{5}{7}$ + 9.1

Answer: 9.81

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:

First, rewrite the fraction as a decimal:

$\frac{5}{7}$ + 9.1

0.71 + 9.1

Add:

0.71 + 9.1 = 9.81

$\frac{5}{7}$ + 9.1 = 9.81

Add. Write your answer as a decimal.

8.4 + -5.5 = Answer: 2.9

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:

8.4 -5.5 = 2.9

Since the number with the greater absolute value is positive, the result must also be positive.

So:

8.4 + -5.5 = 2.9

Add. Simplify your answer and write it as a proper fraction or as a whole or mixed number.

$\frac{2}{6}$ + $\frac{1}{10}$

(use / ) Answer: $\frac{3}{16}$

SOLUTION 1 :

Add:

$\frac{2}{6}$ + $\frac{1}{10}$

= $\frac{3}{16}$

Since the numbers being added are positive, the result must also be positive.

$\frac{2}{6}$ + $\frac{1}{10}$ = $\frac{3}{16}$

2.7 + $\frac{3}{6}$

Answer: 3.2

SOLUTION 1 :

First, rewrite the fraction as a decimal:

2.7 + $\frac{3}{6}$

2.7 + 0.50

Add:

2.7 + 0.50 = 3.2

Since the numbers being added are positive, the result must also be positive.

2.7 + $\frac{3}{6}$ = 3.2
