Mrs.Santos can finish 4 placemats for every 3 that her daughter finishes.If Mrs. Santos finishes 16 placemats in one week,how many placemats in all can mother and daughter finish together in 4 weeks
:
Find out how many placemats Mom can make in 1 day:
16%2F7 placemats per day
:
Find out how many placemats daughter to make in 1 day
3%2F4 * 16%2F7 = 12%2F7 placemats per day
:
Together they can make:
16%2F7 + 12%2F7 = 28/7 = 4 placemats per day
:
4 weeks = 28 days, therefore:
28 * 4 = 112 placemats in 4 weeks
