So we are learning complex fractions and unit rates and i need to do a problem that says simplify 3/6/4

1/8

Step-by-step explanation:

(3/6) / 4

Write 4 as a fraction.

(3/6) / (4/1)

To divide by a fraction, multiply by the reciprocal.

(3/6) × (1/4)

Reduce:

(1/2) × (1/4)

Multiply:

1/8

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
