If 10% of a number is 7, what is 80% of the number?

Zanzabum

Answer:

Step-by-step explanation:

Note that 80% is 8 times 10%.

Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."

Think:

10% of a number is 7,

20% is 14,

50% is 35,

70% is 49, and

80% is 56.

The number of traffic violations in a city increased from 12 to 16 in a month. What is the percent of increase in the number of

Tems11 [23]

Answer:

33%

Step-by-step explanation:

Percentage increase = $\frac{increase}{initial value}$ x 100%

Number of traffic violations increased from 12 to 16.

Initial value = 12

Final value = 16

increase = Final value - Initial value

= 16 - 12

= 4

Percentage increase = $\frac{increase}{initial value}$ x 100%

= $\frac{4}{12}$ x 100%

= $\frac{1}{3}$ x 100%

= $\frac{100}{3}$ %

= 33.3333%

The percentage increase in the number of traffic violations for the month is 33%.
