Question

Please help!!! im not that good in math

Answer 1

Answer:

10. w=2.30

11. 45% will be equal to 0.45  

12. 0.3, 26%, 1/5, 0.09  

15. 57

16. 21.06

17. no of dogs/total no of things  

Step-by-step explanation:

10.  4.6/6 = w/3

       multiplying by 3 on both sides

        (4.6/6)3=w                    

       (0.7666)3=w

         w=2.30

11.    45% will be equal to 0.45 in decimal and all fractions that will be equal                to   0.45 ( e.g some of them are 9/20 = 18/40 = 27/60 = 36/80 = 45/100 )

12. As  26% = 0.26    and 1/5 =0.2 so using the decreasing order answer will be

       0.3, 26%, 1/5, 0.09  

15.   38% of 150 =(150/100) 38

                                =(1.5)38

                                = 57

16.  26% of 81 = (81/100)26

                             = (0.81)26

                            = 21.06

17.  To find the fraction of the circle that represents dogs  as we know the circle is 360 then we will add all the things including the no dogs that will be the total number of things then dividing the no of dogs given by total no of things

 

   The Fraction of circle  that would represent dogs =   No of dogs/ Total no of
