Answer:
9/40
Step-by-step explanation:
- Write down the percent divided by 100 like this:
22.5/100
- Multiply both top and bottom by 10 for every number after the decimal point:
- As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,
(22.5*10)(100*10)= 225/1000
- Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25.
225 ÷ 25/ 1000÷25 = 9/40
If you meant 12 1/4 inches long then your 4 feet and 1 inch long or 49 inches.
I agree with your answer "supplementary". The two angles combine to form 180 degrees, aka a straight angle
