Oliver prepared 45 kilograms of dough after working 5 hours. How much dough did Oliver prepare if he worked for 7 hours

Respuesta :

45 / 5 = 9 kg per hr

for 7 hrs.......9 * 7 = 63 kg <==
You take 45/5 to get the amount of kg per hour which gives you 9kg. You then multiply 9x7 to get 63kg as the total after seven hours.
