Yes i believe to can but im not a expert at math so dont take this awnser to heart
D is the ans. Square root of 49 equals to 7
No. Because the Tenths place is right after the decimal. So he will only have 1 decimal place. Welcome!
Sum means add.
So, we'd need to add
4 5/6 + 3 5/6
5/6 + 5/6 = 10/6, or 1 4/6, or 1 2/3.
4 + 3 = 7
7 + 1 =8
8 2/3 is your answer.
Glad I could help, and good luck!
