There are 28 students in Ivan's class. On a museum trip, 3/4 of the students liked the space-exploration exhibit better than the computer exhibit. Write 3/4 as an equivalent fraction that has a denominator of 28.
I use 28 as the denominator as they said and then I divided the four into 28 which is 7 and multiply that 7 by three and got 21 and then I put the 21 over the 28 (21/28)
