Which quantity is proportional to 18⁄3? check all that are true. 90⁄16 36⁄6 72⁄12 6⁄1 36⁄12

36/6, 72/12, and 6/1

Step-by-step explanation:

18/3=6, so we just need to find the fractions that simplify into 6 (we reduce fractions by dividing the numerator and denominator by the greatest common factor, in this case the number must be whole, so we are just going to divide the numerator by the denominator). 90/16=5.625, it does not equal 6, so it is not proportional to 18/3, this is also true for 36/12=3. 36/6=6 so it is proportional, so is 72/12=6 and, obviously 6/1=6 so it, too, is proportional to 18/3.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
