Tính bằng cách hợp lí nhất:

a) 34750:125 + 65250 : 125           b) 2424 : 8 : 3

Answer 1

a 800

b 101

Answer 2

a)278+522=800

b)303:3=101

Answer 3

a) 800 

b) 101 

Answer 4

a) 34750 : 125 + 65250 : 125     

=   278 + 522

= 800

b) 2424 : 8 : 3

= 303 : 3

= 101

Answer 5

\(\text{a) 34750:125 + 65250 : 125 }\)

\(=\text{100000 }:125\)

\(=\text{800}\)

Answer 6

\(\text{b) 2424 : 8 : 3}\)

\(\text{= 303 : 3}\)

\(\text{= 101}\)

Answer 7

a) \(34750:125+65250:125\)
\(=\left(34750+65250\right):125\)
\(=100000:125=800\)
b) \(2424:8:3\)
\(=2424:\left(8\times3\right)\)
\(=2424:24=101\)

Answer 8

a,=(34750+65250):125

= 100 000 :125

= 800

b, =303 : 3

 =101
