Write 39/40 as a decimal

Given: The fraction

The decimal forms of rational number either end or repeat a pattern.

To convert the given  fractions to decimals you just divide the top by the bottom or divide the numerator by the denominator.

If the division does not come out, you can stop after a certain number of decimal places and round off that number.

Convert a fraction to decimal :

Since fraction and decimal represent the same things because numbers are not whole numbers.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
