simplify
1+ 1/2+1/3

Answer 9

so first you need common denominator....(bottom value)
which will be 6 (2*3)
so :
(6/6)+ (3/6)+ (2/6)
now... add the numerators : (Top values)
it will give you (11/6)
the answer is (11/6)

Answer 10

im sorry but i stil dnt understand

Answer 11

you want all the bottom values to be the same....
therefore you multiply all of them together to get a common denominator... and it is 6
so when you add them.... it will be (6/6) = 1, (3/6)= (1/2) , and (2/6)= (1/3)
so you add 3+6+2 = 11
then put it over the common denominator =6

Answer 12

oka but the equation is 1+ a fration witch is 1/ andthe wholebotom equatio is 2+1/3

Answer 13

then it is 10/7

Answer 14

is the equation (1)+ (1/(2+(1/3)))

Answer 15

take alook

Answer 16

that's what i wrote.


1+ (1)/(2)+(1/3)
now 2+ (1/3) = 7/3
when you divide 1 by 7/3 it flips:
therefore it becomes 3/7
now the equation is
1+ 3/7
common denominator= 7
7/7 + 3/7
= 10/7

Answer 17
