Question

Statistics. Robin ran 5 1/3 mi on Sunday, 2 1/4 mi on Tuesday, and 3 1/2 mi on Friday.How far did she run during the week?

Now I am confused. I add all of these fractions up, right? I'm bad with fractions.
Check my work please
5 1/3 is 64/12 ; 2 1/4 is 27/12 ; 3 1/2 is 14/12
Now add them all up, it's 105/12 brought down is 35/4
Then to turn it into a proper fractionc I divide 35 by 4 which is 8. 35-32 =3
My answer is 8 3/4 miles. IS that correct? If not, can you let me know where I went wrong?
Thanks a bunch! :)

Answer 1

Convert the mixed number to a improper fraction

5 1/3 + 2 1/4 + 3 1/2 =

16/3 + 9/4 + 7/2 =

The common denominator is 12

64/12 + 27/12 + 42/12 =

add the numerator and not the denominator

133/12 =

11 1/2. . .This is the answer

- - - - - - -s-

Answer 2

Using 12 as the lcd

5 1/3=5 4/12 + 2 1/4=2 3/12 + 3 1/2=3 6/12=
5 4/12+ 2 3/12+3 6/12=64/12+27/12+42/12=133/12=
11 1/12 MILES

Answer 3

When we convert 5 1/3 to an improper fraction you multiply 5 * 3 and then add 1... you would put that over 3, so we would convert these fractions as so:

5 1/3 = 16/3
2 1/4 = 9/4
3 1/2 = 7/2

Now we add:
(16/3) + (9/4) + (7/2)
we need to get a common denominator to add these we can use 12.
(16*4/3*4) + (9*3/4*3) + (7*6/2*6)
(64/12)+(27/12)+(42/12) <-- this is your mistake.. not 14/12

which we then get as: 133/12=11 1/12

Answer 4

5 1/3 = 16/3 = 64/12
2 1/4 = 9/4 = 27/12
3 1/2 = 7/2 = 42/12

64/12 + 27/12 +42/12 = 133/12

Answer 5

5 1/3+2 1/4+3 1/2
16/3+9/4+7/2
64/12+27/12+42/12
=133/12=11 1/12 miles

Answer 6

11 and 1/12th is the correct answer (133/12)

5 1/3 = 64/12 correct

2 1/4 = 27/12 correct

3 1/2 = 42/12 there was your mistake

(64 + 27 + 42) / 12 = 133 / 12

.

Answer 7

11 a million/12 miles 5+2+3=10 3 is going into 12 4 cases 4 is going into 12 thrice 2 is going into 12 6 cases 4+3+6=13 13/12= a million a million/12 a million a million/12+10=11 a million/12 12 develop into the backside quantity 3, 4 and 2 ought to all circulate into frivolously.
