The fourth grade had a bubble blowing contest. the diameter of sams bubble was 3/4 of a meter and the the diameter if kate's bubble was 2/3 of a meter. who blew the largest bubble

First, we will need to compare the two fractions. You can use common denominator. As you can see, the two denominators are 4 and 3. 4 x 3 = 12. Now, you can multiply 3/4 x ? to get ?/12 and 2/3 x ? to get ?/12. 3/4 x 3/3 = 9/12. 2/3 x 4/4 = 8/12. 9/12 > 8/12, and 9/12 = 3/4, so Sam is our answer. You can also cross multiply. 3 x 3 = 9 and 2 x 4 = 8. 9 > 8. Hoped this helped!
