Add: 2/3 + 1/6 +2/5
1 1/15
1/3
1 7/30
2/5
Correct Answer : C
First step is to find the least common divisor of denominators 3, 6, and 5 which is 30. Then:
\(\frac{2}{3}+\frac{1}{6}+\frac{2}{5}=\frac{2\left(10\right)+5+2\left(6\right)}{30}=\frac{20+5+12}{30}=\frac{37}{30}=1\frac{7}{30}\)

Correct Answer is D
Explanation
\(\frac{9.6}{0.8}=12\)
Correct Answer is ["540"]
Explanation
A ratio of the form a:b = c:d converted to a proportion equation becomes\( \frac{a}{b}=\frac{c}{d}\)where \(a\ and\ d\neq0\)
Thus, 9:X=5:300 becomes
\(\frac{9}{X}=\frac{5}{300}\)
Cross-multiply to find the value of X
\(9\ast300=5X\)
\(2700=5X\)
Rearranging the above equation
\(5X=2700\)
Divide each side by 5
\(\frac{5X}{5}=\frac{2700}{5}\)
\(X=540\)
The value of X is 540.
Correct Answer is B
Explanation
Multiply numerators and denominators separately
\(\frac{2}{3}\ast\frac{3}{5}\)
3 is common for the two fractions, so it cancels out as follows
\(\frac{2}{3}\ast\frac{3}{5}=\frac{2}{1}\ast\frac{1}{5}=\frac{2}{5}\)
Correct Answer is D
