Question

ricardo's rose bush was 9/12 yard tall, he pruned the rose bush by cutting off 1/9 yard. Ricardo measured the rose bush today, and it had grown 5/6 more after it was pruned. How tall is ricardo's rose bush

Answer 1

The length of the Ricardo's rose bush is 1.47 yards .

Explanation:

The initial height of the rose bush = 9/12 yard = 0.75 yards

The length of the bush which is cut = 1/9 yard

So, the remaining height = The initial height - The pruned part

=
`(9)/(12)  - (1)/(9)  =  (3(9)- 4)/(36) = (23)/(36)`

So, the pruned part of the tree = 23/36 yards in height

Now, the growth of the bush after some time = 5/6 yards

So, the present height of the bush

= Height after it was pruned + The growth

=
`(23)/(36) + (5)/(6)    = (23 + 6(5))/(36)   = (23 + 30)/(36)   = (53)/(36)`

Hence, the length of the Ricardo's rose bush is 53/36( = 1.47) yards .
