the ground. the wheel makes onerevolution every 40
seconds. jenifer boards the ferris
wheel at 2: 00pm. what fractionof the time does
jenifer spend at least 90 feet abovethe
ground?

answer: 12

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
