ok i need help on two questions that i dont understand can someone explain them
4/7 + 3/14
7/10 - 5/8
these are all just turn the equation's denominatior to the CM (common multiple) or you could just use the LCM (least Common multiple), so 7 in the 4/7 and the 14 in 3/14 then multiply both by each other, so you will get 98. Then, multiply 4 by 14, and 3 by 7, so you will now get 56/98 and 21/98, then add to get 77/98.
