It appears you've uploaded an image of a math worksheet. To assist you, I'll first extract the relevant mathematical content from the image and then provide solutions or explanations as needed. I'll get started on that now.The image contains multiple-choice math questions, primarily focused on basic operations with fractions, such as addition, subtraction, multiplication, and division. Here's an outline of the questions present:

Fraction Operations:

1. Addition of Fractions:

   • $\frac{1}{4} + \frac{3}{4}$
   • $\frac{1}{2} + \frac{1}{3}$
   • $\frac{3}{5} + \frac{2}{5}$
   • $\frac{7}{8} + \frac{1}{8}$

2. Subtraction of Fractions:

   • $\frac{3}{4} - \frac{1}{4}$
   • $\frac{5}{6} - \frac{1}{2}$
   • $\frac{7}{10} - \frac{3}{10}$
   • $\frac{9}{12} - \frac{4}{12}$

3. Multiplication of Fractions:

   • $\frac{1}{2} \times \frac{3}{4}$
   • $\frac{2}{3} \times \frac{3}{5}$
   • $\frac{4}{7} \times \frac{2}{3}$
   • $\frac{5}{8} \times \frac{1}{2}$

4. Division of Fractions:

   • $\frac{3}{4} \div \frac{1}{2}$
   • $\frac{7}{8} \div \frac{2}{3}$
   • $\frac{5}{6} \div \frac{1}{4}$
   • $\frac{9}{10} \div \frac{3}{5}$
