Can some one me with these two and tell me if it's multiplication or division

it is unit conversion

1 hm = 100 m

6 hm * 100m/1 hm = 600 m

3m + 600 m

603 m

1 dekameter = 10 meters

9 dam * 10m/1dam = 90 m

5 m + 90 m

95 meters

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
