Candies

There are 150 candies in the bowl. Ivan took seven thirtieths, Charles six fifteenths, and Thomas three-tenths, leaving 150 sweets in the bowl.

Correct answer:

x =  10

Step-by-step explanation:

$$\begin{gathered} q=1-\frac{7}{30}-\frac{6}{15}-\frac{3}{10}=\frac{1}{15}\doteq 0.0667 \\ x=150\cdot q=150\cdot \frac{1}{15}=\frac{150\cdot 1}{15}=\frac{150}{15}=10 \end{gathered}$$
