To copy and complete (a) 1/4 = ? 9/8 = ? 1/2 = ? (b) half = ? quarters (c) whole = ? eighths (d) half = ? eighths (e) 1 quarter = ? eighths (f) 1 whole = ? halves

One whole is equivalent to a fraction where the numerator and denominator are the same. Since we want quarters, the denominator is 4.

$$1 \text{ whole} = \frac{4}{4}$$

So, 1 whole is 4 quarters.

We have $\frac{1}{2}$. To change the denominator to 4, we multiply both the numerator and denominator by 2.

$$\frac{1}{2} = \frac{1 \times 2}{2 \times 2} = \frac{2}{4}$$

So, 1 half is 2 quarters.

Similar to Step 1, 1 whole with a denominator of 8 is $\frac{8}{8}$.

$$1 \text{ whole} = \frac{8}{8}$$

So, 1 whole is 8 eighths.

We have $\frac{1}{2}$. To change the denominator to 8, we multiply both the numerator and denominator by 4.

$$\frac{1}{2} = \frac{1 \times 4}{2 \times 4} = \frac{4}{8}$$

So, 1 half is 4 eighths.

We have $\frac{1}{4}$. To change the denominator to 8, we multiply both the numerator and denominator by 2.

$$\frac{1}{4} = \frac{1 \times 2}{4 \times 2} = \frac{2}{8}$$

So, 1 quarter is 2 eighths.

Similar to Step 1, 1 whole with a denominator of 2 is $\frac{2}{2}$.

$$1 \text{ whole} = \frac{2}{2}$$

So, 1 whole is 2 halves.

The completed answers are:

a) 1 whole = $\boxed{4}$ quarters

b) 1 half = $\boxed{2}$ quarters

c) 1 whole = $\boxed{8}$ eighths

d) 1 half = $\boxed{4}$ eighths

e) 1 quarter = $\boxed{2}$ eighths

f) 1 whole = $\boxed{2}$ halves
