a,3535/3737-x=2121/7474
35/37-x=21/74
x=35/37-21/74
x=49/74
b,x/1968-217/984=187/492
x/1968=187/492+217/984
x/1968=197/328
x=197.1967/328
x=????
\(\frac{3535}{3737}-x=\frac{2121}{7474}\)
\(x=\frac{3535}{3737}-\frac{2121}{7474}\)
\(x=\frac{7070}{7474}-\frac{2121}{7474}\)
a)3535/3737-x=2121/7474

tick nha bạn
a, x=3535/3737-2121/7474
x=49/74
b,x/1968=187/492+217/984
x/1968=197/328=1182/1968
x=1182
Là 49/74
Tick nha Phạm Ngọc Nam Phương
a) \(\frac{49}{74}\)
