Question

Order the number form 3 39/40, 3 19/20,3 19/20

Answer 1

What order should I put it in least to greatest or greatest to least?

Answer 2

For this case we have the following mixed numbers:

$3 \frac {39} {40} = \frac {3 * 40 + 39 * 1} {40} = \frac {120 + 39} {40} = \frac {159} {40} = 3.975$

$3 \frac {19} {20} = \frac {3 * 20 + 19 * 1} {20} = \frac {60 + 19} {20} = \frac {79} {20} = 3.95$

$3 \frac {19} {20} = \frac {3 * 20 + 19 * 1} {20} = \frac {60 + 19} {20} = \frac {79} {20} = 3.95$

It is noted that the last two numbers are the same.

Also, it is observed that:

$3.975> 3.95$

Answer:

Order from highest to lowest:

$3 \frac {39} {40}, 3 \frac {19} {20}$

Order from least to greatest:

$3 \frac {19} {20}, 3 \frac {39} {40}$,
