Question

Jon spent 1/3 of his study time doing math homework and 2/7 preparing for a history exam. What fraction of his study time remains?

Answer 1

Convert the fractions to the Lowest common denominator. In this case it is 21

1/3 = 7/21
2/7 = 6/21

7/21 + 6/21 = 13/21

8/21 of his study time remains

Hope this helps :)

Answer 2

1/3 + 2/7 = 7 + 6 /21 = 13/21

Time remaining is 21-13/21 = 8/21 of the total study time.

Answer 3

This is a fractions least common denominator problem. Your equation is: 1 - (1/3 + 2/7) = your answer . The least common denominator is 3x7=21. So your equation can be expressed as (21/21) -(7/21+6/21)=(21/21)-(13/21)=8/21. So 8/21 of Jon's study time remains. In terms of percentage this is 8 divided by 21 equals 38% of his study time remaining.

Answer 4

1/3 + 2/7 = 7/21 + 6/21 = 13/21 of his study time remains

Answer 5

It simple just find a common denominator- 21 so your two fractions will be 7/21 and 6/21 so you add your numerators and you have 13/21. 21 minus 13 is 8, so Jon has 8/21 left in his study time.

Answer 6

find a common demoninator bud, then it becomes very easy. in this case. the common denominator of 1/3 and 2/7 is 21. 7/21 +6/21 = 13/21, jon has 8/21 of his study time remaining.

Answer 7

1/3 + 2/7 = study time used

First, change the denominator into 21 and you will get
(7 + 6)/21

Then, solve it
(7 + 6)/21 = 13/21

Study time remains
= 21/21 - 13/21
= 8/21 (final answer)

Answer 8

1-1/3-2/7 = 8/21

Answer 9

1/3 = 7/21
2/7 =6/ 21
so 13/21, so time left is 8/21

Answer 10

What shapes do you get once you chop up the sq. with a diagonal? 2 trangles. for the reason that all of us be responsive to the sector is a sq., which skill each and all the facets are equivalent (for this reason, in case you be responsive to one side, you be responsive to each and all the facets). So now you have a trangle with 2 facets equivalent to 60 ft. you are able to now use Pythagorean's theorem: A (squared) + B(squared) = C (squared) A and B are your 2 facets after which you basically remedy for C. good success!
