Hope this helps.  Plz mark brainliest.

Step-by-step explanation:

Let the original fraction be a / b.

a increased by 200%

= a + 200% of a

= a + 200% × a

= a + 2 × a

= 3a

b increased by 150%

= b + 150% of b

= b + 1.5 × b

= 2.5b

The new fraction is 3a / 2.5b

3a / 2.5b = 9 / 10

=> a / b = ( 9 × 2.5 ) / ( 3 × 10 )

= 22.5 / 30

= 45 / 60

= 3 / 4
