Kenya exchanges $150 for british pounds(£). suppose the conversion rate is £1=$1.60. how many pounds should she receive?
£240.00
£160.00
£100.01
£93.75

Actually you would need to divide $150 by $1.60 because the U.S. dollar is over one and a half times the amount of the british pound. So, you would have a lot less British pounds than U.S. dollars and you would end up with £93.75.

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
