Question

Tìm y :

a) 96 - ( 37,5 : y ) = 94,5 

b) \(\frac{6}{13}\): \(\left(\frac{1}{2}+y\right)\)= \(\frac{15}{39}\)

c) \(\frac{y}{2}\)- \(\frac{y}{5}\)+ \(\frac{2}{5}\)= \(\frac{9}{10}\)

Answer 1

\(96-\left(37,5:y\right)=94,5\)

\(37,5:y=1,5\)

\(y=25\)

Answer 2

\(\frac{6}{13}:\left(\frac{1}{2}+y\right)=\frac{15}{39}\)

\(\frac{1}{2}+y=\frac{6}{5}\)

\(y=\frac{7}{10}\)

Answer 3

6/13:(1/2+Y)=15/39

1/2+Y=6/5

y=7/10

Chúc bạn học giỏi k cho mk nha
