Value of

(5\frac{1}{3}-2\frac{2}{3})

right-angles is equal to

Solution:

Concept:

One right angle equals 90°.

Explanation:

First, convert the mixed fractions to improper fractions:

5\frac{1}{3} = \frac{16}{3}

and

2\frac{2}{3} = \frac{8}{3}

Subtract:

\frac{16}{3} - \frac{8}{3} = \frac{8}{3}

This result is in right angles. Multiply by 90° to get degrees:

\frac{8}{3} \times 90° = 8 \times 30° = 240°

Answer:

240° (Option B)
