The Brandywine River is at its flood stage of 9 ft is continuing to rain the next measurement shows that the river has risen 1 and 1/12 ft an additional measurement shows that the river has a risen 1 and 5/12 ft how many more feet does a river need to ride to be at the majors flood stage of 13 ft express your answer in simplest form

Answer 1

To find out how many more feet the river needs to rise to reach the major flood stage of 13 ft, we need to add up the additional measurements already provided.

1 and 1/12 ft + 1 and 5/12 ft

To add these fractions, we need to find a common denominator. The common denominator for 12 and 12 is 12.

1 + 1/12 = 12/12 + 1/12 = 13/12

Now we can add the fractions:

13/12 + 5/12 = 18/12

Now we can simplify this fraction:

18/12 = 3/2

Therefore, the river needs to rise an additional 3/2 ft to reach the major flood stage of 13 ft.
