Convert all fractions to have the same denominator.
To convert, we must find the least common multiple of the two denominators of the fractions:
Multiples of 4: {4,8,12,16,20}
Multiples of 5: {5,10,15,20}
The least common multiple of 4 and 5 is 20.
Multiply the fractions by a number that will result in the denominator being 20:


The equation should now look like this:

Subtract both sides by 8/20 to get w by itself:


The value of w is 7/20.
(x+6)2+(y-10)2=36 , would be your equation.
305/0.305 = 1000
There are 1000ft in 305m.
1. (8/9)/4
8/9 * 1/4 = 8/36= 2/9 paint for each birdhouse
2. ron 1 mile every 20 minutes so 3 mph
1 mile every 24 minutes so ron is the faster walker
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:

When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
