Answer 3

Let's solve these two mixed number addition and subtraction problems step by step:

3. $4 \frac{4}{7} + 6 \frac{1}{4}$

To add these mixed numbers together, you can follow these steps:

Step 1: Add the whole numbers together: $4 + 6 = 10$

Step 2: Add the fractions together. To do this, you need to find a common denominator. In this case, the common denominator for 7 and 4 is 28.

Now, rewrite the fractions with the common denominator: $4 \frac{4}{7} = \frac{4 \cdot 4}{7 \cdot 4} = \frac{16}{28}$ $6 \frac{1}{4} = \frac{6 \cdot 7}{4 \cdot 7} = \frac{42}{28}$

Step 3: Add the fractions with the same denominator: $\frac{16}{28} + \frac{42}{28} = \frac{16 + 42}{28} = \frac{58}{28}$

Step 4: Simplify the fraction if possible. In this case, you can simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 2: $\frac{58}{28} = \frac{29}{14}$

So, $4 \frac{4}{7} + 6 \frac{1}{4} = 10 \frac{29}{14}$

4. $5 \frac{7}{8} - 3 \frac{5}{6}$

To subtract these mixed numbers, you can follow these steps:

Step 1: Subtract the whole numbers: $5 - 3 = 2$

Step 2: Subtract the fractions. Again, find a common denominator, which in this case is 24.

Rewrite the fractions with the common denominator: $5 \frac{7}{8} = \frac{5 \cdot 3}{8 \cdot 3} = \frac{15}{24}$ $3 \frac{5}{6} = \frac{3 \cdot 4}{6 \cdot 4} = \frac{12}{24}$

Step 3: Subtract the fractions with the same denominator: $\frac{15}{24} - \frac{12}{24} = \frac{15 - 12}{24} = \frac{3}{24}$

Step 4: Simplify the fraction if possible. You can simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 3: $\frac{3}{24} = \frac{1}{8}$

So, $5 \frac{7}{8} - 3 \frac{5}{6} = 2 \frac{1}{8}$
