Question

It will take 5715 balloons to float one person. That’s way too many balloons! Let’s use WEATHER BALLOONS instead, which are designed to lift heavier objects.Complete the table with the weight or the number of balloons for each object. Then press “Try it” to see if the objects float.

Answer 1

To complete this table you have to use cross multiplication:

Using the known equivalency, that 3 weather ballons can carry 24 pounds you can calculate the rest:

Flower pot:

3 balloons carry 24 pounds

1 balloon carry x pounds

$x=\frac{24}{3}=8$

The flower pot weights 8 pounds

Bookshelf:

3 balloons carry 24 pounds

6 balloons carry xpounds

$x=\frac{6\cdot24}{3}=48$

The bookshelf weights 48 pounds.

Arm chair:

If 24 pounds are carried by 3 balloons

88 pounds are carried by x balloons

$x=\frac{88\cdot3}{24}=11$

The arm chair can be carried by 11 baloons
