Question

Câu 4: Hãy chứng tỏ rằng các phân số sau bằng nhau:

Answer 1

`37/53`

`3737/5353=[3737:101]/[5353:101]=37/53`

`373737/535353=[373737:10101]/[535353:10101]=37/53`

Vậy `3` p/s đã cho bằng nhau

Answer 2

Ta có:

` 3737/5353 = ( 3737 : 101)/(5353:101) = 37/53`

` 373737/535353 = ( 373737 : 10101)/(535353 : 10101) = 37/53`

` 37/53`

Vậy ` 37/53 = 3737/5353 = 373737/535353 `

Answer 3

rút gọn ta có:
3737/5353=37/53
373737/535353=37/53
Vậy 37/53=3737/5353=373737/535353
chúc hok tốt

 

Answer 4

\(\dfrac{37}{53}=\dfrac{37\times101}{53\times101}=\dfrac{3737}{5353}\)

\(\dfrac{37}{53}=\dfrac{37\times10101}{53\times10101}=\dfrac{373737}{535353}\)

Vậy : \(\dfrac{37}{53}=\dfrac{3737}{5353}=\dfrac{373737}{535353}\)

Answer 5
