True. just like Texaschic101 said DV= M
Answer:
The key is finding a common # on the bottom (aka: a common 'denominator')
once you do this, you can easily add and subtract them!
Step-by-step explanation:
EX:
1/2 + 2/3 = ?
<u>*EASIEST TRICK!!*</u>
take your 2nd denominator: (3) and multiply it by the entire (1st fraction): 1/2
<em>(when we MULTIPLY fractions, it is easy as pie, we can just multiply across the top and across the bottom) in this case, we will multiply both top and bottom by the 2nd denominator (3)</em>
(1 x 3)/(2 x 3) = 3/6 <em>(3/6 is another way of saying 1/2, so we're good!)</em>
now take the 1st denominator (2), and multiply the entire 2nd fraction by that:
(2 x 2)/(3 x 2) = 4/6
<em>now we have 6 on the bottom of both! time for the magic:</em>
3/6 + 4/6 = 7/6
but wait! (that means we have 7 slices of a 6-piece pie! ...so we <em>actually </em>have, 1 full (6-piece pie) and 1 slice leftover! <em>(awww yeeea)</em>
<em>so, 7/6</em><em> --> </em><em>1 </em><em>(full pie) </em><em>1/6 </em><em>(leftover!)</em>
<u><em>now to put it all back together:</em></u>
1/2 + 2/3 = 1 & 1/6
The other person did not explain so I will:
(68+79+74)= 221/3 =73.7
80 x 4 = 320
320-221 = 99
He must get 99 on his 4th test.
Thanks
Answer:
At 10:30 A.M.
Step-by-step explanation:
A college offers shuttle service from Dickson Hall or Lot B to its campus quad.
At 9:10 A.M the first shuttle leaves from their locations for the campus.
If the shuttles leave from Lot B every 10 minutes and leave from Dickson Hall every 12 minutes, then both the shuttles will leave their origin at the same time after 60 minutes.
This is because 60 is the smallest multiple of 10 and 12 which is common for them.
Therefore, 10:30 A.M. is the next time when both shuttles will depart for the campus at the same time. (Answer)
