Question

5 50/100 - 2 72/100= ​

Answer 1

For this case, we convert the mixed numbers into fractions:

$5 \frac {50} {100} = \frac {100 * 5 + 50} {100} = \frac {550} {100} = \frac {55} {10} = 5.5$

$2 \frac {72} {100} = \frac {100 * 2 + 72} {100} = \frac {272} {100} = 2.72$

Now, rewriting the expression in three equivalent forms we have:

$\frac {550} {100} - \frac {272} {100} = \frac {278} {100}$

$5.5-2.72 = 2.78\\2 \frac {78} {100}$

Answer:

$2 \frac {78} {100}$
