think about the mathematical process you use as you solve the following problems. show your work.
a. If there are 100 students in a room and 40 of them are boys, how many are girls?
b. if there are 17 blue and white stripes on the flag and 9 of them are blue, how many are white?
c. if there are 250 pennies and dimes in a box and 130 of them are pennies, How many are dimes?
d. now it is time to generalize. Imagine you know how many items you have in a collection of two types of things. If you know how many of one of the items you have,How could you find how many of the other item you have?

Best ResponseYou've already chosen the best response.1right! now, I'm sure you've noticed the pattern in these problems. question d is asking you about that pattern. d. now it is time to generalize. Imagine you know how many items you have in a collection of two types of things. If you know how many of one of the items you have,How could you find how many of the other item you have?

Best ResponseYou've already chosen the best response.1if you know the total, and you know how many of one type you have, then to find the other type, you subtract total  first type = second type
