Question

Allison buys a spool of thread for sewing. There are 8 yards of thread on the spool. She uses 1.5 meters. How much thread is left on the spool in meters? Round your answer to the nearest thousandth, if necessary.

Answer 1

We know that one yard is equal to 0.9144 meters, then:

$8yd=8(0.9144m)=7.3152m$

Allison used 1.5 meters, then we have:

$7.3152-1.5=5.815$

Therefore there are 5.815 meters left.
