When you're looking to simplify a fraction, the best thing to do is to find a common factor between the two numbers.
In this case, 10 is a common factor, so therefore, divide both sides by 10.
30/10= 3
40/10= 4
Therefore, the fraction in its simplest form is 3/4

Answer:
Step-by-step explanation:
- <em>This is a cyclic quadrilateral (all vertices on the same circle)</em>
<u>Opposite angles are supplementary:</u>
- ∠A + ∠C = 180°
- ∠B + ∠D = 180°
<u>Find x:</u>
- x + 5 + x - 7 = 180°
- 2x - 2 = 180°
- 2x = 182°
- x = 91°
<u>Find D:</u>
- ∠D = x - 14°
- ∠D = 91° - 14° = 77°
<u>Find B:</u>
Answer:
12 boys
Step-by-step explanation:
Multiply the ratio numbers by 6 and you have
boys : girls = 2 : 3 = 12 : 18
There are 12 boys in the class.
<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
