solve in attached image this is my test ? ( I give 100 more point to correct answer pls )

Answer 1

Answer:

(i) LCM of 3,6,9=18

Now let us change each of the given fraction into an equivalent fraction having 18 as the denominator.

(2/3)x(6/6)=(12/18)

and (5/6)x(3/3)=(15/18)

and (1/9)x(2/2)=(2/18)

Now,

=(12/18)+(15/18)−(2/18)

=(12+15−2)/18

=(27−2)/18

=(25/18)

=[1(7/18)]

(ii) Convert mixed fraction into improper fraction, and then find the difference.

=[4(1/2)]=(9/2)

=[2(1/4)]=(9/4)

LCM of 1,2,4=4

Now, let us change each of the given fraction into an equivalent fraction having 4 as the denominator.

=(9/2)×(2/2)=(18/4)

and =(9/4)×(1/1)=(9/4)

and =(8/1)×(4/4)=(32/4)

Then,

=(32/4)−[(18/4)−(9/4)]

=[(32−18−9)/4]

=[(32−27)/4]

=(5/4)

=[1(1/4)]

(iii) First we convert each mixed fraction into an improper fraction.

⇒[8(5/6)]=(53/6)

also ⇒[3(3/8)]=(27/8)

and ⇒[1(7/12)]=(19/12)

Then,

(53/6)−(27−8)−(19/12)

LCM of 6,8,12=24

Now, let us change each of the given fraction into an equivalent fraction having 24 as the denominator.

=[(53/6)×(4/4)]=(212/24)

also =[(27/8)×(3/3)]=(81/24)

and =[(19/12)×(2/2)]=(38/24)

Now,

=(212/24)−(81/24)−(38/24)

=[(212−81+38)/24]

=[(250−81/24)]

=(169/24)

=[7(1/24)]
