1^2 is 1+4 times 1 is 5 plus 4 is 9
2^2 is 4+4 times 2 is 12 plus 4 is 16
3^2 is 9+ 4 times 3 is 21 XXXXXXX==> 2 times
You would have to have common demoniators to add.
8/10 can be turn into 80/100 by multiplying the denominator and nominator by ten
75/100+80/100, you add the nominators ONLY, dont change the denominator.
75+80=155
so your answer would be 155/100
1.7n +1
I think the is the answer
I hope this helps :)
Answer:
2, 1/3 inches in 3/4
basically you multiply the denominator to match the other problem so 1/3 becomes 4/12 and 3/4 becomes 9/12
so there are 2 1/3 inches in 3/4, this is a sort of rough explanation I reccomend going on Khan Academy and looking for something to help you there
The value of 2 in 2,783 is thousand. The value of 2 in 7,283, is hundred.
So it is one times the value.
