Question

Alan bought 20 yards of fencing. he used 5.9 yards to surround one flower garden and 10.3 yards to surround another garden.write the amount remaining as a fraction in simplest form.

Answer 1

step
`1`

Determine the total amount of fencing used by Alan

`5.9+10.3=16.2\ yards`

step
`2`

Determine the remaining amount of fence

Subtract
`16.2` from
`20`

`20-16.2=3.8\ yards`

step
`3`

convert the amount remaining as a fraction in simplest form

`3.8= 3+0.8 =3+(8)/(10) = 3(4)/(5) \ yards`

therefore

the answer is

`3(4)/(5) \ yards`

Answer 2

The answer for this question is that the remaining amount fencing left after Alan has completed his garden will be 3 4/5 yards. This can be worked out, by first determining that the overall amount of fencing Alan used was 5.9 + 10.3, to create a total of 16.2. The remaining amount of fence can therefore be calculated by subtracting 16.2 from 20 to get 3.8 yeards. As a fraction this would then by written as 3 8/10, which can then be simplified down to get your answer of 3 4/5.
