let the number is 10x + 3.

then sum of its digits = x + 3.

from given condition, we have

x+3 = (1/7)* (10x + 3)

=> 7x + 21 = 10x + 3

=> 3x = 18

=> x = 6

therefore the number is 63.

Vesnalui [34]

Complete question is;

Jackson has to repaint some classroom bookcases. He has 2 gallons of paint. All the bookcases are the same size and each requires 2/5 gallon of paint. How many bookcases is he able to repaint with the amount of paint?

Answer:

5 books

Step-by-step explanation:

Jackson has 2 gallons of paint

Now, for us to find the number of bookcases the Jackson will be able to repaint if each bookcase requires 2/5 gallon, we will just divide 2 by 2/5

Thus;

Number of book cases Jackson will be able to repaint = 2 ÷ 2/5

Thus gives; 2 × 5/2 = 5 books
