B. 6/9=18/36? no
C. 9/18=16/36? no
D. 35/120=75/250? no
another way is if a/b=c/d, then (ad)/(bc)=1 or ad=bc

What order from least to greatest 3/5 3/7 3/4
Answers
Hey there!
To order them from least to greatest, we can convert them each into decimals. To convert a fraction into a decimal, simply divide the numerator by the denominator.
1)
To convert into a decimal, simply divide the numerator which is 3, by the denominator which is 5.
3 ÷ 5 = 0.6
So, is equal to 0.6 as a decimal.
2)
To convert into a decimal, simply divide the numerator which is 3, by the denominator which is 7.
3 ÷ 7 = 0.43 approximately
So, is equal to 0.43 as a decimal. (approximately)
3)
To convert into a decimal, simply divide the numerator which is 3, by the denominator which is 4.
3 ÷ 4 = 0.75
So, is equal to 0.75 as a decimal.
⇒ 0.6 ⇒ 0.43 ⇒ 0.75
So, from least to greatest, the order is: , ,
