(13) Geeta had 30 problems for homework. She worked out [tex]$\frac{2}{3}$[/tex] of them. How many problems were still left to be worked out by her?

Sagot :

Sure, let's work out the problem step-by-step:

1. Total Problems Given:
Geeta started with a total of 30 problems for her homework.

2. Fraction Solved:
She managed to solve [tex]\(\frac{2}{3}\)[/tex] of the total problems.

3. Number of Problems Solved:
To find out how many problems she solved, we multiply the total number of problems by the fraction she solved:
[tex]\[ \text{Number of problems solved} = 30 \times \frac{2}{3} \][/tex]

4. Number of Problems Left:
After solving some problems, we subtract the number of problems she solved from the total to find out how many are left:
[tex]\[ \text{Number of problems left} = 30 - \text{Number of problems solved} \][/tex]

After performing these calculations:

- Geeta solved 20 problems.
- The number of problems remaining is 10.

Therefore, Geeta still has 10 problems left to be worked out.
