3 over 4 + 1 over 8

Mathematics
1 answer:
Dmitry [639]3 years ago
3 0

Answer:

7/8

Step-by-step explanation:

Start by finding a common denominator. In this case you can turn the 4 into an 8 by multiplying by 2 but you have to do the same to the 3

2(3/4)= 6/8

Step 2: Add 6/8 + 1/8

6/8+1/8= 7/8

The explicit rule for a sequence is given. an=4n−1 What is the recursive rule for the sequence?
Gnom [1K]

Answer:

a_{n+1}=a_n+4

Step-by-step explanation:

Have in mind the definition of the term a_n=4\,n-1, and now work on what the term a_{n+1} is based on the previous definition:

a_{n+1} = 4\,(n+1)-1\\a_{n+1}=4\,n+4-1

In the next step do NOT combine the numerical values, but try to identify the a_n term (4\,n-1) in the expression (notice the use of square brackets to group the relevant terms):

a_{n+1}=4\,n+4-1\\a_{n+1}=[4\,n-1]+4\\a_{n+1}=a_n+4

So now we have the term "a_{n+1}" defined in a recursive manner based on the previous term "a_n"

Solve. 3 1/4 - 1 5/8
erik [133]

Step 1. Convert 3 1/4 to an improper fraction.

3 * 4 + 1/4 - 1 5/8

Step 2. Simplify 3 * 4 to 12

12 + 1/4 - 1 5/8

Step 3. Simplify 12 + 1 to 13

13/4 - 1 5/8

Step 4. Convert 1 5/8 to an improper fraction.

13/4 - 1 * 8 + 5/8

Step 5. Simplify 1 * 8 to 8

13/4 - 8 + 5/8

Step 6. Simplify 8 + 5 to 13

13/4 - 13/8

Step 7. Find the Least Common Denominator (LCD) of 13/4, 13/8

LCD = 8

Step 8. Make the denominators the same as the LCD

13 * 2/ 4 * 2 - 13/8

Step 9. Simplify. Denominators are now the same

26/8 - 13/8

Step 10. Join the denominators

26 - 13/8

Step 11. Simplify

13/8

Step 12. Convert to a mixed fraction

1 5/8
