Answer:
0.5:1
Step-by-step explanation:
laps:minutes
So we can find how much Ronald runs in 2 minutes, by dividing 6:12 (or 6/12) by 6. This will give you 1:2 (One lap = 2 minutes).
But you're looking for 1 minute, so with 1:2, you have to divide them by 1/2, so it will be 0.5:1.
So, 9 out of 10 students prefer class, so, obviously, it would not be 100. It would be 150. So in conclusion, 50 students prefer lunch over math class, whilst 150 other students prefer math class over lunch.
The numbers are both equal because, 6.80 is six and eight hundredths, and 6.8 is six and eight tenths. When writing decimals any zero added to the end of the number has no value, 8/10 as a fraction is equal to 80/100 if simplified, so Nicky and Marta wrote equal numbers. :)
