 373737 / 474747+ 5757 / 4747

=37/47                +   57/47

=      94/47

ta có:

\(\frac{373737}{474747}=\frac{37}{47}\)

\(\frac{5757}{4747}=\frac{57}{47}\)

=>\(\frac{37}{47}+\frac{57}{47}\)

\(=\frac{94}{47}\)

 373737 /474747 + 5757 / 4747

=\(\left(37\cdot10101\right):\left(47\cdot10101\right)\left(57\cdot101\right):\left(47\cdot101\right)\)

\(\left(37-47\right)\cdot10101+\left(57-47\right)\cdot101\)

373737 / 474747+ 5757 / 4747

=37/47                +   57/47

=      94/47

37*10101 / 47*10101 + 57*101 / 47*101

= 37 / 47 + 57 /47

= ( 37 + 57 ) / 47 = 2

373737 / 474747 + 5757 / 4747 

= 37 / 47 + 57 / 47

= 94 / 47

Trả lời :

373737 / 474747 + 5757 / 4747 

= 37 / 47 + 57 / 47

= 94 / 47

\(\frac{373737}{474747}+\frac{5757}{4747}\)

\(=\frac{10101x37}{10101x47}+\frac{101x57}{101x47}\)

\(=\frac{37}{47}+\frac{57}{47}\)

\(=\frac{94}{47}\)

\(=2\)

Lời giải:
$\frac{373737}{474747}+\frac{5757}{4747}$

$=\frac{373737:10101}{474747:10101}+\frac{5757:101}{4747:101}$

$=\frac{37}{47}+\frac{57}{47}=\frac{94}{47}=2$
