Answer and Explanation :

1) Number
(65)/(18)

Converting improper fraction into mixed fraction,

Divide 65 by 18

65 ÷ 18 = 3 with a remainder 11.

11 ÷ 4 = 2 with a remainder of 3

So, We write down the 3 and then write down the remainder 11 above the denominator 18.

i.e.
(65)/(18)=3(11)/(18)

2) Number
2(5)/(7)

Converting mixed into improper fraction,

Step 1 - Multiply the whole number part by the denominator

i.e.
7* 2=14

Step 2 - Add that to the numerator

i.e.
14+5=19

Step 3 - The result is


2(5)/(7)=(19)/(7)

3) Perform the operation and write the answer in simplest form.

a)
(4)/(7)*(3)/(11)

Multiply,


(4)/(7)*(3)/(11)=(12)/(77)

b)
(6)/(10)/(12)/(7)

Divide,


(6)/(10)/(12)/(7)=(6* 7)/(10* 12)


(6)/(10)/(12)/(7)=(7)/(20)

c)
5(1)/(7)*3(1)/(9)

First convert mixed into improper,


(36)/(7)*(28)/(9)

Multiply,


(36)/(7)*(28)/(9)=16

d)
6(3)/(7)/ 1(13)/(14)

First convert mixed into improper,


(45)/(7)*(27)/(14)

Divide,


(45)/(7)*(27)/(14)=(45* 14)/(7*27)


(45)/(7)*(27)/(14)=(10)/(3)
