Total population = 308,827,000

Percent of kids under 5 = 6.5%

Total population of kids under 5 = x

solving for x

x = 6.5% × 308,827,000

remember that z% = z/100. so 6.5% would be 6.5/100

x = 6.5 ×
308,827,000

100 1

the zeros cancel out

x = 6.5 ×
308,827,000

100 1

100 1

x = 6.5 × 3,088,270

x = 20,073,755

So there are 20,073,755 children under 5

##### Regin,

##### 6.5% can be written as a decimal. In order to do this move the decimal point 2 places to the left and remove the % sign. Therefore 6.5 is written .065 as a decimal. Then you can multiply 308,827,000 and .065 in order to find your answer.

Remember to round the nearest whole number.

I hope this helps.

Express the percent as a decimal value by dividing by 100. Remember that 6.5% means 6.5 per 100 = 6.5/100 = 0.065.

Multiply the population by the decimal equivalent of 6.5%, that is by 0.065.

308,827,000 x 0.065 = 20,073,755 children under age 5.
