Answer:

________________________________

$step\:1$

$\frac{1}{ \sqrt{3} - \sqrt{2} }$

write the equation

________________________________

$step\:2$

$\frac{1 \times ( \sqrt{3} + \sqrt{2}) }{ (\sqrt{3} - \sqrt{2} ) \times (\sqrt{3} + \sqrt{2}) }$

multiply both numerator and denominator by √3+√2

________________________________

$step\:3$

$\frac{ \sqrt{3} + \sqrt{2} }{ ( 3 ) - ( 2 ) }$

after multiplying numerator with √3+√2 we get→√3+√2

after multiplying denominator we get 3-2

________________________________

$step\:4$

$\frac{ \sqrt{3} + \sqrt{2} }{1}$

after subtracting 3 with 2 we get →1

________________________________

hence denominater is rationalized✓

2. US$ 1.7135

Brrunno [24]

Answer:

1577.8 US dollars are received for 1127 UK pounds.

5669.5 UK pounds are received for US$7937.3.

Step-by-step explanation:

The questions are solved by proportions, using a rule of three.

How many US dollars are received for 1127 UK pounds?

1 UK pound = 1.4 US dollars

1127 UK pounds - x US dollars

Applying cross multiplication:

$x = 1127*1.4 = 1577.8$

1577.8 US dollars are received for 1127 UK pounds.

How many UK pounds are received for US$7937.3?

1 UK pound = 1.4 US dollars

x UK pounds - 7937.3 US dollars

$1.4x = 7937.3$

$x = \frac{7937.3}{1.4}$

$x = 5669.5
$

5669.5 UK pounds are received for US$7937.3.
