Two ways:
=
and 1/4 = 25%
Another way.
300 = n% of 1200
Problem - we can't move n% back two place to change it to a decimal since we don't know what n is. Solution - move the decimal back on the 1200 two places because since of means x, it doesn't matter. Sample .45 x 32 = 45 x .32 Notice that the decimal can be place on either number and it results in the same answer.
So 300 = 12n (1200 moved back 2 places)
now divide by 12
<u>300</u> = <u>12n
</u>12 12 and once again n=25(%)<u>

3, 11, 19, 27, 35...
a = 3
d = 11-3 = 8
a20 = a + 19d = 3 + 19*8 = 3 + 132 = 135
HOPE IT HELPS!
Answer 1.5
Divide 9/6= "Answer"
Where did the 9 come from?
There are 12in in a foot so 3/4 = 9in
we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side
So
Multiply both sides by 2
2A = h(x+y)
Divide both sides by h
2A/h = x+y
Subtract y from both sides
