Question

Pls, help me this is due at 4:00!!!

Answer 1

You have to get LCD of all of the fractions, so this would be 70.
1/2x(35/35)=35/70
4/5x(14/14)=56/70
1/7x(10/10)=10/70
(35+56+10)/70=101/70
Then, you have to convert to a mix number
101/70=1 31/70

Answer 2

161/70

Explanation:

you have to find the lowest common multiple of 5,2 and 7 which is 70.then times the numerator by the multiple you have to times to get 70.eg 2×35 is 70 so multiply 1 by 35 which is 35.then add them all up.

35/70 + 56/70 + 70/70 = 161/70

hope this helps
