The drama club spent a total of 40 hours practicing for the school play. 10% of the time was spent doing dress rehearsals. How many hours did the drama club spend doing dress rehearsals

4 hours

Step-by-step explanation:

We need to find 10% of 40 hours:

10%*40

Convert 10% to a fraction, as I find it makes the math simpler. To do this, we can simplify put 10 over 100 as any percentage is that number over 100:

Simplify the fraction:

They spent 4 hours doing dress rehearsals

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
