Help please. anything would help.

Option a) 1/5 is most closely to 0.

1/5 is the closest to 0 out of all the answers, and is the only one that would round downwards to Zero.

5/10=1/2 50%

7/12 is unable to be simplified, but is 58%

10/11 can not be simplified, but = rounds up to 91%

you cannot round anything above 50% downwards.

i dont know

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
