If the question is what I think it is, then it's simple. All you need to do is divide 420 by 15; and you'll get the answer: 28.
Answer:
I think you can
Step-by-step explanation:
Well if you have 48 pics of flowers and 36 pictures of scenery and you want an equal amount of pictures of the scenery, you want to start out by just seeing what number divides evenly into both, in this case, it is four.
We multiply the fraction of 3/4 to the whole number 24 to get the equivalent number of the fraction.
24 * 3/4 = (24 * 3)/4 = 72/4 = 18
3/4 of 24 is 18.
There are 18 blue tiles out of the 24 tiles used.
