Question

Divide 33 photos into two groups so the ratio is 4to 7

Answer 1

`\textsf{Let the number of two photos in each groups be 4x and 7x.}\\\textsf{Then,}\\\textsf{Total number of photos = 33}\\\textsf{or, 4x + 7x = 33}\\\textsf{or,\ 11x = 33}\\\textsf{or,\ x = 3}\\\therefore\ \textsf{Number of photos in first group = 4x = 4(3) = 12}\\\therefore\ \textsf{Number of photos in second group = 7x = 7(3) = 21}`
