Answer:
a. 8/24 or 1/3 a day
b. 45/60 or 3/4 a hour
c. 1/7 of a week
d. 4/12 or 1/3 a year
Step-by-step explanation:
Simply divide by the conversion you want to set.
60 seconds is 1 hour
24 hours is 1 day
7 days is 1 week
3-4 weeks per month (depending on the month and year)
12 months a year
Answer in fraction form: x = 55/4
Answer in decimal form: x = 13.75
Both forms are equivalent, but they say it in a slightly different way.
===========================================================
Work Shown:
AC/QY = CD/YW
(x+5)/15 = 5/4
4(x+5) = 15*5
4x+20 = 75
4x = 75-20
4x = 55
x = 55/4
x = 13.75
------------
Explanations:
- The first step is possible because the polygons are similar. Similar figures have their corresponding sides be in the same proportion or ratio. Note how side AC has the double red angle (at point A) and a single red angle (point C). The side QY has the same idea in the same order. This is why AC corresponds to QY. The ratio AC/QY is the same as CD/YW.
- In the second step, I plugged in the expressions that the diagram shows. This is the substitution property.
- On step 3, I cross multiplied. The general format is A/B = C/D cross multiplies to A*D = B*C.
