Question

Gabby is helping her mom hang streamers in their living room for a party. They start with 10 yards of streamers. Gabby hangs 8 feet of streamers, and her mom hangs 16 feet of streamers. How many yards of streamers do they have left?

Answer 1

First, we need to convert the units of streamers into a common unit, so we can add the amounts hung by Gabby and her mom. 1 yard is equal to 3 feet, so we can convert the 10 yards of streamers into feet:

10 yards * 3 feet/yard = 30 feet

Now, we can add the amounts hung by Gabby and her mom:

30 feet + 8 feet + 16 feet = 54 feet

Finally, we can convert the total amount back into yards:

54 feet / 3 feet/yard = 18 yards

So, Gabby and her mom have 18 yards of streamers left.
