Answer:

#=102 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 xx1000 = 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 2/3# feet.

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

#3 # feet = #1# yard.

#306 2/3 div 3 = 102 2/9# yards.

We could have done one calculation:

#1# yard = #36# inches.

#3680 /36 = 102 8/36# yards

#=102 2/9# yards
