The word phrase for this is <u>"Three times the difference of t and one."</u>
Here is an example,
<span>The ratio of boys to girls in the class was 4:5. There were 24 people in the class. How many boys? How many girls?
-------
4:5 is the same as 4x:5x where 4x is # of boys and 5x is # of girls.
----
Equation:
4x+5x = 24
9x = 24
x = 24/9

7.50÷2
Since we know a triangle only has 180 degrees we can say:
99+3x+x+5=180
Then we can solve for x:
4x+104=180
4x=76
x=19
Y= 2(1/4)^2
2×(1/4)= .5
2×.5= 1
So the answer is 1
