Question

so sánh hai số x,y sau đây:

x= (42 - 4,2.10+76:7,6) : (o,01. 0,1)

y= (689,7 + 0,3) : ( 7,4 :0,2 - 2,2 - 1,5)

Answer 1

 

\(x=\left(42-4,2.10+76:7,6\right):\left(0,01:0,1\right)\)

\(x=\left(42-42+10\right):\left(0,1\right)\)

\(x=10:\left(0,1\right)\)

\(x=100\)

\(y=\left(689,7+0,3\right):\left(7,4:0,2-2,2-1,5\right)\)\(y=690:\left(33,3\right)\)\(y=\frac{2300}{111}\)

 

Answer 2

So sánh : 

\(100>\frac{2300}{111}\)   hay   \(x=y\)

Answer 3

Mình nhầm : \(100>\frac{2300}{111}\)   hay  \(x>y\)
