1. If 3/5 of the class is girls, and 1/2 of the girls in the class are wearing
dresses, what fraction of the class are girls with dresses? *

1 1/10

Step-by-step explanation:

3/5 + 1/2 Can't be plused, so we make the denominator the closest number both 5 and 2 go into, 10. So now we need to change the 3 and 1 by timesing them the same numbers we timesed the 5 and 2. We times 3 by 2 and the 1 by 5, making the fractions 6/10 + 5/10 = 11/10. we turn this improper fraction into a mixed number, and the answer is 1 1/10.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
