How do I do this question

aliya0001 [1]

Answer:

Step-by-step explanation:

Join OB.

∠A=∠A (common)

$\frac{AP}{AO} =\frac{\frac{1}{2} AO}{AO} =\frac{1}{2} \\\frac{AQ}{AB} =\frac{\frac{1}{2} AB}{AB} =\frac{1}{2} \\\frac{AP}{AO} =\frac{AQ}{AB}$

∴ ΔAPO and ΔAOB are similar.

$\frac{PQ}{OB} =\frac{1}{2} \\$

∠P=∠O

∠Q=∠B

So PQ║OB

Similarly RS║OB

∴PQ║RS

What is 9/10-2/3 in simplest form

Serggg [28]

Answer: The simplified form of above expression is $\frac{7}{30}$

Step-by-step explanation:

Since we have given that

$\frac{9}{10}-\frac{2}{3}\\$

We need to solve the above expression to get the simplified answer:

1) Take the L.C.M. of 10 and 3.

L.C.M. of 10 and 3 = 30

2) Make the denominator 30 for each of the fraction .

$\frac{9}{10}\times \frac{3}{3}=\frac{27}{30}\\\\and\\\\\frac{2}{3}\times \frac{10}{10}=\frac{20}{30}$

3) Take the difference between them:

$\frac{27}{30}-\frac{20}{30}\\\\=\frac{7}{30}$

Hence, the simplified form of above expression is $\frac{7}{30}$
