Which fraction is a proper fraction. 7/6 ,4/3 ,1/2 or 3/3

Step-by-step explanation: In this list showed here, 1/2 and 3/3 would both be proper fractions. Remember, a proper fraction is a fraction whose numerator is less than or equal to its denominator. Proper fractions represents values that are less than or equal to 1.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

b. b < 1 might be the correct answer
