Lena is making a collage with pictures of all her closest friends and newspaper clippings that are about their interests. She has found three clippings for each friend’s pictures. It takes her six drops of glue to stick down each clipping. Lena has already glued her seven closest friends’ pictures. How many drops of glue will she need for the newspaper clippings for her collage?

How many clippings does Lena have? ** Lena has 3 clippings per friend, so she has 3 * 7 = <<3*7=21>>21 clippings to glue.
How many drops of glue will Lena need? ** She needs 6 drops of glue per clipping, so she will need 6 * 21 = <<6*21=126>>126 drops of glue.
