From here we can see that 4(90°) = 360°. In other words, a quadrilateral has a total of 360°.
We can use this fact to determine the missing angle in any quadrilateral or four sided shape.
First find the answer to the equation
3 • 3/4 = 9/4
Reduce the fraction to a mixed number
9/4 = 2 1/4
Now determine which 2 whole numbers it is between
2 1/4 lies between 2 and 3
Answer:
3/4 so math
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
17/20 the 17 is the part, and the 20 is the whole
17/20 = x/100
cross multiply
17*100= 1,700 divide by 20
=85
The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning
100% - 85% = 15%
