Answer:

23/20

Step-by-step explanation:

You have to get each fraction to a common denominator, which in this case is 20. So you multiply the numerator and denominator of 2/5 both by 4. Then multiply the numerator and denominator of 3/4 by 5. So you get 8/20 + 15/20 = 23/20

18b+27=477

18b. =477-27=450
