Jon and Jim painted a fence Jon painted a quarter of the fence and Jim painted five twelfths of the fence how much of the fence did they paint

jon & jim painted 8/12 of the fence

Step-by-step explanation: first, convert. one quarter is equal to 1/4, & 1/4 of 12 (since Jim painted 5/12) is 3/12. now we know that Jon painted 3/12 of the fence & that Jim painted 5/12 of the fence (we already knew this, didn't we?). all you have to do now is add: 3/12 + 5/12 = 8/12. so, jon & jim painted 8/12 of the fence.

- hope this helps

b). 4320 have a nice day

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
