Respuesta :

336 ants because there are 4 1/4 inches in an inch and 4 x 84 is 336
How many ants would be:           Length of picnic blanket / length of ant

                                           =   84 inches  / (1/4)

                                           = 84 * 4 =    336

So the blanket is 336 ants long.

Hope this is clear.
