It takes one pipe 10 minutes to fill a tank with water. It takes a second tank 15 minutes to fill the tank. With both pipes open and the tank empty, how long will it take to fill the tank? please make a chart thank you

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?

What is the sum of these mixed numbers 2 1/8 + 4 3/8
