6 + y/33 = 7/11
y/33 = 7/11 - 6
y/33 = -59/11
y= -59/11 x 33
y= -177
=> Y/33= 7/11- 6= -59/ 11
=>Y= -59/11 . 33= -177
Vậy x= -177
x+6/33=7/11
7+y/33=9/11
tìm x biết: 6+x/33 = 7/11
1+2+3+4+5+6+7+8+9+11+2+33+44+56+77
\(\frac{6+x}{33}\)=\(\frac{7}{11}\)
1=11 2=22 3=33 4=44 5=55 6=66 7=77...........hỏi 11 = bao nhiêu
a,6/15=8/y
b,x/5=6/10
c,2/3=12/x
d,24/26=x/12
e,14/56=1/x
g,x/125=2/2
h,6+x/33=7/11
i,5/7=y/147
k,5/7=y/147
l,4/x=y/21=28/49
m,3*x-5/60=2/3
n,2/3*x=3*9
o,24/120=x/5
Tính nhanh:
\(\frac{33}{2}+\frac{33}{6}+\frac{33}{18}+\frac{33}{54}+\frac{33}{162}+\frac{33}{486}\)
\(\frac{2}{3\cdot5}+\frac{2}{5\cdot7}+\frac{2}{7\cdot9}+\frac{2}{9\cdot11}+\frac{2}{11\cdot13}+\frac{2}{13\cdot15}\)
Tìm X:
\(\frac{X+6}{33}\)= \(\frac{7}{11}\).
