Answer:

3 dollars and 9 cents.

Step-by-step explanation:

From the question given above, the following data were obtained:

Total amount = 20 dollars

Amount for gift A = 9 7/10 dollars

Amount for gift B = 6 2/5 dollars

Amount for gift C =?

The amount of money she has left for gift C can be obtained as follow:

A + B + C = 20

9 7/10 + 6 2/5 + C = 20

Change to improper fraction

97/10 + 32/5 + C = 20

(97 + 64)/10 + C = 20

161/10 + C = 20

Collect like terms

C = 20 – 161/10

C = (200 – 161)/10

C = 39/10

Change to mixed fraction

C = 3 9/10 dollars

C = 3.9

C = 3 dollars and 9 cents

Therefore, Kathy had 3 dollars and 9 cent for gift C

Seven-ninths of the pencils in a box are yellow. Three-tenths of the yellow pencils are sharpened. What fraction represents the

jek_recluse [69]

Answer:

7/30

Step-by-step explanation:

We are given that Seven-ninths (7/9) of the pencils in a box are yellow and three-tenths (3/10) of the yellow pencils are sharpened.

To find the fraction that represents sharpened yellow pencils, we find the product of the the fraction of yellow pencils and the fraction of yellow pencils that are sharpened.

That is:

=> (7 / 9) * (3 / 10)

=(7 * 3) / (9 * 10)

= 21 / 90

= 7 / 30

7/30 represents the fraction of sharpened yellow pencils.
