Math Problem Statement

-1/10 = 3/x - 1/2

Solution

The image you've provided contains a mathematical comparison of fractions: 1210=3211\frac{12}{10} = \frac{3}{2} \cdot \frac{1}{1}. To evaluate if this statement is correct, we'll simplify and compare both sides.

Simplification

The left fraction 1210\frac{12}{10} can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 2:

1210=12÷210÷2=65\frac{12}{10} = \frac{12 \div 2}{10 \div 2} = \frac{6}{5}

The right side 3211\frac{3}{2} \cdot \frac{1}{1} is already in its simplest form, but let's multiply the fractions:

3211=3121=32\frac{3}{2} \cdot \frac{1}{1} = \frac{3 \cdot 1}{2 \cdot 1} = \frac{3}{2}

Comparison

Now, comparing the simplified forms:

6532\frac{6}{5} \neq \frac{3}{2}

Thus, the original statement 1210=3211\frac{12}{10} = \frac{3}{2} \cdot \frac{1}{1} is incorrect because 65\frac{6}{5} is not equal to 32\frac{3}{2}.
