Converting 6000 grams to kilograms gives 6 kg.

The probability of drawing a green marble is 1/10.

Total mixture = 25 L.
Ratio = 4 parts Arabica beans, 1 part Robusta beans (total 5 parts).
Amount of Arabica beans = (25 L / 5 parts) * 4 parts = 20 L.

dividing 4 by 3 = 1.33m

Total mixture = 50 cubic meters.
Ratio = 4 parts topsoil, 1 part peat moss, 5 parts compost (total 10 parts).
Amount of peat moss = (50 cubic meters / 10 parts) * 1 part = 5 cubic meters.

Three books at £7.50 each is £22.50, and two pens at £2.50 each is £5, totaling £27.50.

Dividing 360 by 6 gives each part as 60.

Solving 15x = 225 for x gives x = 15.

If there are 10 boys in a class of 20 students, the other half, or 10/20, must be female, which is 1/2.

If £45 represents 90% of the original price (after a 10% discount), the original price was £50 (since £45 is 90% of £50).

30% of 150 is 45.

5 is not a factor of 36, as it does not divide evenly into it.

Total mixture = 12 L.
Ratio = 4 parts water, 1 part lemon juice, 1 part mint syrup (total 6 parts).
Amount of water = (12 L / 6 parts) * 4 parts = 8 L.

Total mixture = 36 kg.
Ratio = 2 parts sugar, 3 parts flour, 4 parts butter (total 9 parts).
Amount of flour = (36 kg / 9 parts) * 3 parts = 12 kg.

Adding 125 minutes to 2:15 PM results in 4:40 PM.

1. 1. Find the difference in quantity: Subtract the number of apples from the number of oranges to find out how many more oranges Joe has.
      $\text{More Oranges}=\text{Oranges}-\text{Apples}=8-6=2$ 

       

1. 1. Calculate the percentage: The difference needs to be expressed as a percentage of the number of apples to find out by what percentage the number of oranges is more than the number of apples.
      $\text{Percentage More}=\left(\frac{\text{More Oranges}}{\text{Apples}}\right)\times 100$ 

1. 1. $\mathrm{}$ 

      $\text{Percentage More}=\left(\frac{2}{6}\right)\times 100$

      Percentage More = 13×100

1. 1. 
      $\text{Percentage More}=33.33\mathrm{\%}$ 

       

So, Joe has 33.33% more oranges than apples.

Estimating the sum gives approximately 1200.

Cars in garage A = 30 x 4 = 120

Cars in garage B = 30 x 2.5 = 75

Therefore, Garage A has (120 - 75 = 45) more cars than garage B

An equilateral triangle has 3 lines of symmetry.

Total mixture = 50 L.
Ratio = 3 parts nitrogen, 2 parts phosphorus, 5 parts potassium (total 10 parts).
Amount of phosphorus = (50 L / 10 parts) * 2 parts = 10 L.

Dividing 150 miles by 3 hours gives an average speed of 50 mph.

Total mixture = 30 L.
Ratio = 3 parts lavender oil, 2 parts chamomile oil, 5 parts almond oil (total 10 parts).
Amount of lavender oil = (30 L / 10 parts) * 3 parts = 9 L.

Doubling 123 gives 246, and adding 50 to this gives 296.

Cross-multiplying to solve 2/3 = ?/9 gives 6 as the missing numerator.
