Question

While eating lunch, Vivian ate 65% of the carrots she had in her bag. There were 20 carrots in her bag before she ate any. How many carrots did Vivian have left in her bag after she ate?

Answer 1

Answer:

Vivian would have 7 carrots left to spare if she ate 65% of the carrots in the bag.

Step-by-step explanation: Since 65% of 20 carrots equals 13 carrots, we would do 20 - 13. In which equals 7 so she has 7 carrots left in fer bag

Equation: 20-x=?

Solution: 20 - 13=7

Answer 2

Answer:

7 carrots

Step-by-step explanation:

In order to find how many carrots are left, you first must find what is 65% of 20.  A good way to do that is by using cross multiplication.

      We cross multiply 20 × 65 and get 1,300.

      Then we take 1,300 and divide it by the 100 left in the equation.

       After we get the answer to the division problem (13), we subtract 13 from the 20 carrots Vivian originally had. That gives us our final answer, which is 7. So Vivian has 7 more carrots left.

              $\frac{x}{20}$  =  $\frac{65}{100}$    

         20×65 = 1,300

         1,300 ÷ 100 = 13  

         20 - 13 = 7
