Because you are given the ingredients for one batch, and you want the ingredients for four batches, you can multiply all of the original quantities by 4 to find the answers.

1 1/2 × 4
To do this, first convert 1 1/2 into a mixed number by doing 1 × 2 = 2, and 2 + 1 = 3, which would be the numerator. This then gives you
3/2 × 4/1, which simplifies to 12/2, which means your answer is 6.

1 × 4 = 4

1 × 4 = 4

3 × 4 = 12

3/4 × 4 = 3
(you cancel out the "/4" because you're multiplying by 4)

1 × 4 = 4

1/3 × 4/1 = 4/3

I hope this helps!

Answer:

84.9%

Step-by-step explanation:

First we need to calculate the total number of people. Total number of people will be the sum of all the given frequencies of all classes. There are 9 classes in total that are shown on the histogram

So,

Total number of people = 40 + 40 + 35 + 35 + 25 + 25 + 25 + 25 + 15 = 265

Now we need the number of people who took less than 40 seconds. This will be equal to sum of all frequencies below the time 40 seconds. i.e.

Number of people who took less than 40 seconds = 40 + 40 + 35 + 35 + 25 + 25 + 25 = 225

Formula to calculate percentage is:

$Percentage = \frac{\text{Desired Part}}{\text{Total}} \times 100\%$
