Question

Product of two no.Is 11520 and quotient is 9/5 find difference

Answer 1

Answer:

Step-by-step explanation:

let the numbers are a, b

ab = 11520

a/b=9/5

to find a-b or b-a

a=9b/5, put this value of a in ab=11520

9b/5 × b = 11520

b² = 11520/9 × 5

b² = 1280 × 5

b² = 5×2×2×8×8 × 5

b=√(5×5×2×2×8×8)

b= 5×2×8

b=80

a= 9/5 ×80

a= 144

so the difference is 144-80 = 64
