What is 20% by 37 decreased
Ghella [55]

Answer:

<u><em>37 decreased by 20% is </em></u><u><em>29.6.</em></u>

Step-by-step explanation:

<u><em>To do this, what we do is simply </em></u><u><em>take 20% of 37 and subtract it from 37.</em></u>

<u><em>20% of 37.</em></u><u><em> A trick to easily figure this out is </em></u><u><em>multipling 37 by 20 and dividing by 100.</em></u>

<u><em>37*20 = 740</em></u>

<u><em>740 / 100 = 7.40</em></u>

<u><em>37 - 7.40 = 29.6</em></u>

<u><em>37 decreased by 20% is </em></u><u><em>29.6.</em></u>
