Answer:

1. 561

2. 57%

3. 175

4. $ 27

5. 1000 g

6. 78%

Step-by-step explanation:

1. 3300 x .17 = 561

2. 7980/14000 = .57

.57 x 10% = 57%

3. 70 ÷ 40% = 175

175 x .40 = 70

4. 30 x .10 = 3

30 - 3 = $ 27

5. 26% of x = 260 gm

26

100 x 100 = 260

x = 260 x 100

26

x = 26000

26

x = 1000 g

6. 50 - 11 = 39

39/50 = .78

.78 x 100% = 78%

50 x .78 = 39

Hope it helps!
