Question

a. $5 + 0 = 0$
b. $15 \cdot 0 = 0$
c. $1.4 + 2.7 = 4.1$
d. $\frac{2}{3} \cdot \frac{5}{9} = \frac{7}{12}$
e. $4\frac{2}{3} = 5 - \frac{1}{3}$

Explanation:

Step1: Verify Option A

$5+0=5
eq 0$, so A is false.

Step2: Verify Option B

$15 \cdot 0=0$, so B is true.

Step3: Verify Option C

$1.4+2.7=4.1$, so C is true.

Step4: Verify Option D

$\frac{2}{3} \cdot \frac{5}{9} = \frac{10}{27}
eq \frac{7}{12}$, so D is false.

Step5: Verify Option E

$5 - \frac{1}{3} = \frac{15}{3} - \frac{1}{3} = \frac{14}{3} = 4\frac{2}{3}$, so E is true.

Answer:

B. $15 \cdot 0 = 0$, C. $1.4 + 2.7 = 4.1$, E. $4\frac{2}{3} = 5 - \frac{1}{3}$
