calculate 30% of 40 and 25% of 20 and add them together what would we get?

12 + 5 = 17

30% of 40 = 12
25% of 20 = 5
12 + 5 = 17
Because 20 is a half of 40, so 25% of 20 = 12.5% of 40
so, we can conclude that 17 is 42,5% of 40
Or, because 40 is double of 20
we can conclude that 17 = 85% of 20

30*40/100 + 25*20/100 =
12 +5 =
17

40 + 20 = 60
.3 .25 x
multiply the number with the corresponding percentage

12 + 5 = 60x
17=60x
x=17/60
x = 28.33 %



other solution
30% of 40 and 25% of 20
=30% of 20 + 30% of 25% of 20
all of them are 20 so just get the average
=(30+30+25)/3
=85/3
=28.33%

17

30% of 40%
= 30/100 X 40%
= 12%

25% of 20%
= 25/100 X 20%
= 5%

12% + 5%
= 17%

.3(40) + .25(20) = ???
12 + 5 =??
17=??

40 x 30% + 20 x 25%
= 40 x 30/100 + 20 x 25/100
= 1200/100 + 500/100
= 12 + 5
= 17

30/100 x 40 = 12
25/100 x 20 = 5
12 + 5 = 17

Hope this helps (:

30/100 x 40 = 12
25/100 x 20 = 5
12 + 5 = 17
answer is 17

NOTE: u have to find the percentages Separately then add them together...
