Plz help me and explain how you got the answer plz

1 answer:

3 0

The decrease was 3. (from 30 down to 27)

Always calculate the decrease as a percent of the ORIGINAL number.

3/30 = 0.1

To change a decimal to a percent, move the point 2 places that way ==> .

0.1 = 10% .

When you go from 30 to 27, that's a decrease of 10% .

paula spent 3/8 of her allowance on clothes and 1/6 on entertainment. what fraction of her allowance did she spend on other item

MArishka [77]

We have to calculate the fraction of Paula`s allowance that she spent on other items if she already had spent 3/8 on clothes and 1/6 on entertainment. First we have to add: 3 / 8 + 1 / 6 = ( LCD is 24 ) = 9 / 24 + 4 / 24 = 13 / 24. Then : 1 - 13 / 24 = 24 / 24 - 13 / 24 = 11 / 24. Answer: She has spent 11 / 24<span> of her allowance on other items. </span>
