Do you have a problem adding fractions?

(1/2) + (3/4) + (1/3) is the answer

The lowest common denominator is 12 (and if you don't know how to get that you can send me a message for further help).

(6 + 9 + 4)/12 = 19/12 = 1 7/12 pounds

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
