Question

Cost of a book is 7 3\4 no of books can be purchased with rupees 69 3\4

Answer 1

cost of 1 book= 7 3/4

let no of books be purchased = x

rupees given 69 3/4

therefore 7 3/4*x = 69 3/4

x= 69 3/4 / 7 3/4

now change the mixed fraction into improper fraction

69 3/4 = 276/4

7 3/4 = 31/4

x= 276/4 /31/4 the four can be transferred up to become multiplied

x= 27*4/4 /31 = 1104/4/31 = 8.9....
