How do I add 12 ½ +16¾=

Step-by-step explanation:

Make the denominators equal after simplifying the denominators*. The denominators are currently 2 and 4. So you can just make your life easier by making the denominator of the first number a 4. Multiply both sides by 2.

1. Simplify

12*2+1 = 25/2

25/2*2/2 = 50/4

2. Simplify second number

16*4+3 = 67/4

3. Add the improper fractions

50/4 + 67/4 = 117/4

Terms:

*denominators - the bottom number of a fraction

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
