Answer: 25/40
Step-by-step explanation:
To keep the numerator odd, we need to multiply by an odd number. The denominator will always stay even. We also need to multiply the denominator so that it's more than 30 and less than 50. There are 3 multiples of 8 between 30 and 50: 32, 40, and 48. 32 and 48 = 8 x 4 and 8 x 4 respectively, so they won't work because the numerator will become even. Thus, 40 will only work for the denominator. 40 = 8 x 5. We can now find our fraction:
= 5/8 x 5/5
= (5x5)/(8x5)
= 25/40
