Simplify this map scale

1cm: 5km

This problem belongs to comparing quantities.

as we have two different units cm and km .so we need to convert any one of the units to same unit.i am converting km to cm here .

1km=1000m

100cm=1m

so 1000m=100000 cm

so 5km=5000m=500000 cm

1cm:500000 cm =1/500000 is the ratio to fraction form.As we having same units on both numerator and denominator it will cancels.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
