<span>This is a conversion problem. You are given one meter of yellow ribbon
and 28 centimeters of blue ribbon. You are required to find for the number of
centimeters of ribbon she needs. Note that there are 100 centimeters in one
meter. So you have to convert the one meter of yellow ribbon into 100
centimeters of yellow ribbon. Then add the ribbons, 100 plus 28 equals 128
centimeters of ribbon. So Audrey needs 128 centimeters of ribbon all in all.</span>
