Jones takes 8 hours , therefore in one hour he paints a fraction of 1/8
smith takes 6 hours, thus in one hour he paints a fraction of 1/6
When working together they paint a fraction of 7/24 in an hour.
After 2 hours they will have painted a fraction of (7/24) ×2 = 7/12
The remainder will be 5/12 which will be undertake by smith alone.
Smith will therefore take 5/12 ×6/1 = 2.5 hour or 2 hours 30 minutes

3/5 / 3/7
= 3/5 * 7/3
= 7/5 or 1 2/7
The answer is $3.57 because you must multiply 2.55 by 140 then divide that by 100 to find your answer hope this helps.
<span>sin(2x)= 2sin(x)cos(x)
can you finish the rest or need more help?
sin(6/5) should be the answer
so we have 2 sin(0.6)cos(0.6)
we know its sin (2x) identity
x=0.6
so its sin(2*0.6)</span>
