(\frac{37}{4} - \frac{37}{5} )\div \frac{37}{5} = \frac{148}{20} - \frac{185}{20} \div \frac{37}{5} = \frac{ - 37}{20} \div \frac{37}{5} = \frac{ - 37}{20} \div \frac{185}{20} =

[tex] - \frac{0.2}{20} = 0.01[/tex]

A=(37/4 -37/5):37/5
A=185/20-148/20):37/5
A=37/20:37/5
A=37/20x5/37
A=1/4

B =(25/8+53/20-26/5)X5/23
B =(125/40+106/40-208/40)X5/23
B=(231/40-208/40)X5/23
B=23/40x5/23
B=1/4

C=(30/5+7/5)x12/37:12
C=37/5x12/37:12
C=12/5:12
C=12/5x1/12
C=1/5

D=4a+8b+c
D=4x1/4+ 8x1/4+1/5
D=1+2+1/5
D=5/5+10/5+1/5
D=16/5

Sper ca te am ajutat
