Can someone me with the answer to this. st. augustine grass can grow at the rate of 4 over 7 centimeter per week. how many weeks will it take the grass to grow 12 over 7 centimeters? explain your answer using expressions and words.

Per week: +4/7

Goal: 12/7

You can look at it without fractions, since all of the denominators (the bottom numbers) are the same. Grass grows at 4 cm per week, how long until it reaches 12cm? 12/4 = 3 weeks

Or we can math it out:

4/7 + 4/7 + 4/7 = 12/7

4/7 centimeters per week
how many weeks will it take to grow 12/7 centimiters
4/7 times x weeks=12/7
multiply both sides by 7/4 to clear fraction (1/2 times 2/1=2/2=1 simplifies)

4/7 times 7/4 times x=12/7 times 7/4
1x=12/4 times 7/7
1x=3 times 1
x=3

3 weeks is the answer

 (basically 12/4=3)

6/ 11 = 0.545454 so your answer is55%

Idk what the answer is bc i don't get it
