Soni has 196 pencils. If she puts equal amounts of pencils into eight boxes, she has four pencils left. How many pencils does she put in each box?

First take 196/8 which equals 24.5, now you know it cannot be anything greater than 24.5, so lets try 24 pencils in each eight boxes, well 24x8=192, this means you have 4 pencils remaining after putting an equal amount of 24 pencils in each 8 box
