Answer 1

The correct answers are B, D and E

Step-by-step explanation:

The best way to find if each of the statmenet is true or false is to find the percentage in each case. To do this, follow this general formula: Total number / 100 (100 representes the total) x specific percentage. Now, let's apply this formula in each statement

A)

30 ÷ 100 = 0.3 x 15 = 4.5 (This statement is false)

B)

80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)

C)

50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)

D)

60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)

E)

20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)
