First, we need to find the original ratio of 7th to 6th

6th = 12

7th = 21

21:12

Then find any common factors

21: 1,3,7,21

12: 1,2,3,4,6,12

divide 21 and 12 both by 3

21/ 3 = 7

12 / 3 = 4

7:4 is your ratio

For every 7 students in 7th grade, there are 4 students in 6th grade.

Convert 750ft to metre

Angelina_Jolie [31]

One meter is composed of approximately 3.28 feet. To convert a certain measure in feet to meter, divide the number by 3.28. From the given above, using dimensional analysis and the conversion factor,

(750 ft) x (1 m/ 3.28 ft) = 228.66 m

Thus, 750 ft is approximately 228.66 in meters.
