Step-by-step explanation:

if your dong 40% of 45 t will be 18

18

Step-by-step explanation:

To solve we fist need to figure out what 40% is in decimal form. To do this we have to move the decimal point to the left 2 spaces.

40% -> 0.40

Then we can multiply...

45 · 0.40 = 18  (This means that 40% of the total 45 students is 18).

total of apples - take away four
