which equations will 3/5 make true select all the correct choices A. 7/20 +_ =19/20 b. _ 3/10=3/15 c.1/2+2/3=_ d.1/10+1/2=_ e._+1/20=9/20
Verify each option
so
option A) 7/20 +_ =19/20
substitute the value of 3/5
remember that
3/5 and 12/20 are equivalent
substitute
7/20+12/20=19/20
19/20=19/20 -----> is true
equation A is a solution
option B) 3/5 +3/10=3/15
3/5 is equivalent tp 6/10
so
6/10+3/10=3/15
9/10=3/15 -----> is not true
option C) 1/2+2/3=_
1/2+2/3=3/5
(3+2*2)/6=3/5
7/6=3/5 ----> is not true
option D) 1/10+1/2=_
1/10+1/2=3/5
we have that
1/2=5/10
3/5=6/10
substitute
1/10+5/10=6/10
6/10=6/10 -----> is true
option D is a solution
option E) _+1/20=9/20
3/5+1/20=9/20
we have that
3/5=4/20
substitute
4/20+1/20=9/20
5/20=9/20 -----> is not true
therefore
answer is
option a and option d
