Question

which expressions can you use to find the number of eighths in 2 wholes? choose all the correct answers. $2\div\frac{1}{8}$ $2\times 8$ $2\div 8$ $2\times\frac{1}{8}$

Explanation:

Step1: Understand the question

We need to count how many $\frac{1}{8}$ are in 2.

Step2: Relate to division

To find how many parts $\frac{1}{8}$ fit into 2, use division: $2 \div \frac{1}{8}$

Step3: Convert division to multiplication

Dividing by a fraction = multiplying by its reciprocal: $2 \div \frac{1}{8} = 2 \times 8$

Step4: Verify the result

$2 \times 8 = 16$, which matches the 16 eighths shown in the visual. The other options $2 \div 8 = \frac{1}{4}$ and $2 \times \frac{1}{8} = \frac{1}{4}$ do not give the number of eighths in 2.

Answer:

A. $2 \div \frac{1}{8}$, B. $2 \times 8$
