Question

1-(5\(\frac{5}{36}\)+y-7\(\frac{7}{18}\)):15\(\frac{3}{4}\)=0

Answer 1

\(1-\left(5\frac{5}{36}+y-7\frac{7}{18}\right):15\frac{3}{4}=0\)

=>\(1-\left(\frac{185}{36}+y-\frac{133}{18}\right):\frac{63}{4}=0\)

=>\(1-\left(-\frac{9}{4}+y\right).\frac{4}{63}=0\)

=>\(1-\left(-\frac{1}{7}+\frac{4}{63}y\right)=0\)

=>\(1+\frac{1}{7}-\frac{4}{63}y=0\)

=>\(\frac{8}{7}-\frac{4}{63}y=0\)

=>\(63.\frac{8}{7}-63.\frac{4}{63}y=63.0\)

=>\(72-4y=0\)

=>\(4y=72-0\)

=>\(4y=72\)

=>\(y=72:4\)

=>\(y=18\)

Answer 4

1-(185/36+y-133/18):63/4=0

(185/36+y-133/18):63/4=0

185/36+y-133/18=0

185/36+y=0+133/18

185/36+y=133/18

y=133/18-185/36

y=266/36-185/36

y=81/36=9/4

Vậy y=9/4
