Order decimals from least to greatest .. 1.09, 1.901,1.9,1.19
Nuetrik [128]
The easiest way to do this is to write the decimals with equal amount of places after the dot and you'll see it more clearly:

1.09 = 1.090
1.901 = 1.901
1.9 = 1.900
1.19 = 1.190

So from the least to the greatest:

1.090
1.190
1.900
1.901

In a form you gave at the beginning:

1.09 < 1.19 < 1.9 < 1.901

Destin walked 2km and Jane walked 4,000 ft. What is the approximate combined distance they walked? Note: 1 Foot (ft) is equal to
Anna11 [10]

Answer: Option C.

Step-by-step explanation:

The data is:

Destin walked 2km

Jane walked 4000ft.

Let's write both of those in the same units.

The data given is:

1ft = 0.0003048km.

and 4000ft is 4000 times that:

4000ft = 4000*1ft = 4000*0.0003048km = 1.22km

Then if we add those, we get:

Total distance = 2km + 1.22km = 3.22km

So we can already discard option D.

Now, we know that:

1km = 0.6214 miles.

then 3.22 km is 3.22 times that amount:

3.22km = 3.22*1km = 3.22*(0.6214 mi) = 2 miles

The correct option is C.
