1/5+3/10 x=4/5

1 answer

To solve the equation 1/5 + 3/10 = 4/5 for x, we need to isolate x on one side of the equation.

1/5 + 3/10 = 4/5

To add fractions, we need the same denominator:

2/10 + 3/10 = 4/5

Combining the numerators:

5/10 = 4/5

Now, we can cross-multiply:

5 * 5 = 4 * 10

25 = 40

Since 25 is not equal to 40, the equation 1/5 + 3/10 ≠ 4/5 is not true.
