If michael's family has 210 acres and each cow take 1/3 acre for grazing, how many cattle could their farmland support?

630 cows

Step-by-step explanation:

To find the number of cows the land can support, we take the number of acres and divide by the number of acres per cow

210 acres ÷1/3 acre per cow

Copy dot flip

210 * 3/1 = 630 cows

the answer to this question is in the pic

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
