Question

Y% of the three-fourth of _______ is 3 400 yz.​

Answer 1

Step-by-step explanation:

The answer is 45.

n×23×34×15=15

⟹6n60=15

⟹n10=15

⟹10(n10)=15×10

⟹n=150

30%=310 so

Answer 2

Answer:

1/y²z

Step-by-step explanation:

Y% is nothing but Y/100

Y% of the three-fourth is Y/100*3/4 = 3Y/400

Now, a certain no. is multiplied with 3Y/400 to get 3/400YZ

Let that number be x

(3Y/400)*x = 3/400YZ

               x = 3/400YZ*400/3Y

               x = 1/yz * 1/y

               x = 1/y²z

So, the answer is 1/y²z
