Step-by-step explanation:
Repeated Addition:
3/4 +3/4 +3/4 +3/4 = 12/4 = 3
The denomenator will stay the same (4). So all you need to do is add the numerator (top. number in the fracton, 3)
It is the same logic as a basic multiplication problem using reapeted additon
(see example below:)
10 * 5 = 50
10 +10 +10 +10 +10 = 50
Multiplication:
4 * 3/4 = 12/4 = 3
You should not multiply the denomerator. You should only multiply the numerator. So you multiply 4 times 3 and get 12. So, you should get 12/4.
I apologize for my bad spelling.
Answer:
78, 1275
Step-by-step explanation:
a) 12th= 78
b) 50th=1275
Answer:
see below
Step-by-step explanation:
Closed under addition, subtraction and multiplication
Not closed under division :-
for example 3/4 = 0.75 which is not an integer
