Answer 2

Answer:

3/5

Step-by-step explanation:

One number is 9/10

So let the other number be x

Therefore,

x+ 9/10 =3/2

x= 3/2- 9/10

( making denominators same by multiplying both numerator and denominator with LCM, that is, 10.)

Therefore,

x = 15/10- 9/10

= 6/10

simplyfying 6/10 gives 3/5

Hope this helps
