Question

Gulf side gifts has 48 box’s of post cards to sell there are 24 postcards in each box is the shop sells 3 boxes of postcards how many post cards does the shop have left

Answer 1

First figure out how many post cards you have in all (48 x 24 = 1,152)
And now they sell 3 boxes
And there are 24 postcards in each box so
(24 x 3 = 72)
So 1,152 minus 72 is 1,080,
The shop has 1,080 post cards left.
