Jeremy's mom is making him expand her flower bed. It was originally 3 ft wide by 7 ft long. She wants him to keep the same proportions but wants the new flower bed to be 21 ft long. How wide is the new flower bed?

9 ft

Step-by-step explanation:

the original proportion is 3 : 7

we can let the new width be 'x'

the new proportion would be x : 21

21 / 7 = 3 so then you multiply 3 by 3 as well to get your answer of 9 ft as the width
