403 / 4 = 100.75 
to get any fraction of a number, as long as the numerator is 1 in the fraction, just divide by the denominator. In this case it's 4. Since you can't place .75 of a puzzle piece, she's placed 100 pieces in the puzzle.

SKIP # 14 SHOW ALL WORK PLEASE AND I WILL GIVE BRAINLY AND 77 points for it
babunello [35]

Answers:

11. 48%

12. 25%

13. 36%

15. 93%

16. 99%

17. 0.16%

18. 160%

19. 85%

Work for 19:

The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.

Percentage of 40% of what number = 34?

40% of what number = 34 is equivalent to: 40% × ? = 34

--------------------------

40% × ? = 34

? =

34 ÷ 40% =

34 ÷ (40 ÷ 100) =

(100 × 34) ÷ 40 =

3,400 ÷ 40 =

85

Proof:

If 40% × 85 = 34 =>

Divide 34 by 85...

... And see if we get as a result: 40%
