Fraction Addition 6Ed44B
1. Problem: Calculate the value of the expression $3 \times \frac{2}{5} + \frac{2}{3}$.
2. Formula and rules: To add fractions, they must have a common denominator. Multiplication of a whole number and a fraction is done by multiplying the whole number by the numerator.
3. Calculate $3 \times \frac{2}{5}$:
$$3 \times \frac{2}{5} = \frac{3 \times 2}{5} = \frac{6}{5}$$
4. Now add $\frac{6}{5} + \frac{2}{3}$:
Find the least common denominator (LCD) of 5 and 3, which is 15.
5. Convert fractions to have denominator 15:
$$\frac{6}{5} = \frac{6 \times 3}{5 \times 3} = \frac{18}{15}$$
$$\frac{2}{3} = \frac{2 \times 5}{3 \times 5} = \frac{10}{15}$$
6. Add the fractions:
$$\frac{18}{15} + \frac{10}{15} = \frac{18 + 10}{15} = \frac{28}{15}$$
7. Final answer: $\frac{28}{15}$, which is not among the options given, so let's re-check the problem statement.
Re-examining the original expression: $3 (2/5) + 2/3$ means $3 \times \frac{2}{5} + \frac{2}{3}$.
Calculations are correct, so the answer is $\frac{28}{15}$.
Since none of the options match $\frac{28}{15}$, the problem might have a typo or the options are for a different expression.
Therefore, the correct result of the given expression is $\frac{28}{15}$.
