$= 102 \frac{2}{9}$ yards = $102$ yards and $8$ inches

#### Explanation:

When working out word problems, first decide on what operation(s) you need to do.

Each of 1,000 ribbons needs to be $3.68$ inches.
The total length of ribbon required will be a multiplication.

$3.68 \times 1000 = 3 , 680$ inches

However, this is not practical, inches is too small a unit, so convert to a larger one. $12$ inches = $1$ foot

$3680 \div 12 = 306 \frac{2}{3}$ feet.

Again this is not practical. Convert to a larger unit, yards:

$3$ feet = $1$ yard.

$306 \frac{2}{3} \div 3 = 102 \frac{2}{9}$ yards.

We could have done one calculation:

$1$ yard = $36$ inches.

$\frac{3680}{36} = 102 \frac{8}{36}$ yards

$= 102 \frac{2}{9}$ yards
