Answer:
3 = 9
4 = 10
Step-by-step explanation:
Note: Consider 84 instead of 83 because the value of x is a decimal value of 83 which is not possible.
Given:
Compound ratio of 7:5 and 8:x is 84:60.
To find:
The value of x.
Solution:
Compound ratio of 7:5 and 8:x is 84:60.
By cross multiplication, we get
Divide both sides by 1420.
Therefore, the value of x is 8.
20 is the median since it’s the middle. Median means second quartile. 3rd quartile = Find the median of the 2nd half. It would be in between 24 and 27 which means it is 25.5 in other words, 25 1/2
1a. 5/10 can be simplified to 1/2. (5 divided by 5 is one, 10 divided by 5 is 2.)
1b. 9/12 can be simplified to 3/4. (9 divided by 3 is 3, 12 divided by 3 is 4.)
1c. 12/18 can be simplified to 2/3. (12 divided by 6 is 2, 18 divided by 6 is 3.)
1d. 9/24 can be simplified to 3/8. (9 divided by 3 is 3, 24 divided by 3 is 8.)
1e. 27/90 can be simplified to 3/10. (27 divided by 9 is 3, 90 divided by 9 is 10.)
1f. 40/48 can be simplified to 5/6. (40 divided by 8 is 5, 48 divided by 8 is 6.)
