37*10101 / 47*10101 + 57*101 / 47*101
= 37 / 47 + 57 /47
= ( 37 + 57 ) / 47 = 2

Trả lời :
373737 / 474747 + 5757 / 4747
= 37 / 47 + 57 / 47
= 94 / 47

Lời giải:
$\frac{373737}{474747}+\frac{5757}{4747}$
$=\frac{373737:10101}{474747:10101}+\frac{5757:101}{4747:101}$
$=\frac{37}{47}+\frac{57}{47}=\frac{94}{47}=2$
A=37/47+57/47
A=94/47
A = 373737/474747 + 5757/4747
A = 379494/479494
A = 2
