Bethany lives in London.
Her cousin Pierre lives in Paris.
They are going on holiday together to America.

Pierre is offered an exchange rate of 1 euro to 1.07 dollars.
Bethany is offered an exchange rate of £1 to 1.25 dollars.

Bethany says, "Using these exchange rates, £1 is worth euros."

1.17 Euros

Step-by-step explanation:

Given that £1 equals 1.25 dollars then to get the value of 1 dollar will be 1/1.25=£0.8

If 1 Euro equals to 1.07 dollars and knowing that 1 dollar is equal to £0.8 then 1.07 dollars will be equal to 1.07*0.8=£0.856

1.07 dollars=£0.856=1Euro

1.25 dollars =£1=x Euros

Cross multiplying the last two parts then

£0.856* x Euros=£1*1Euro

X=1/0.856=1.1682242990654

Rounding off to 2 decimal places, x=1.17

Therefore £1 is worth 1.17 Euros

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
