( 37 . 13 - 13 ) : ( 24 + 37 . 12 )
= ( 481 - 13 ) : ( 24 + 444 )
= 468 : 468
= 1
\(\left(37.13-13\right):\left(24+37.12\right)\)
\(=468:468\)
\(=1\)
\(\left(37.13-13\right):\left(24+37.12\right)\)
\(=468:468\)
\(=1\)
\(\left(37.13-13\right):\left(24+37.12\right)\)
\(=468:468\)
\(=1\)
Đặt phép tính trên là A ta có:
A=\(\frac{37\cdot13-13}{24+37\cdot12}\)=\(\frac{37\cdot\left(12+1\right)-13}{24+37\cdot12}\)=\(\frac{37\cdot12+37-13}{24+37\cdot12}\)=\(\frac{37\cdot12+24}{24+37\cdot12}\)= 1
