Mortar is made with clay and heap of sand. The recipe for mortar calls for equal parts (1kg) of clay and heap of sand to make one mortar.

However, one clay is 2kg and one heap of sand is 20kg. Knowing this we can calculate the total clay and heap of sand needed to make the amount of mortar we want.

The mortar recipe calls for:

• 1kg of clay which is half of a full clay, or .5
• 1kg of heap of sand which is one twentieth of a full heap of sand, or .05

Using these values we can calculate the number of full clay and full heap of sand required.

Prerequisites:

• Mortar is the amount of mortar we need.
• Number is the calculated number of ingredients we need.
• Kg is calculated the amount needed in kg
• .5 is a half a clay, which is 1kg or the recipe amount needed per mortar
• .05 is a twentieth of a heap of sand, which is 1kg or the recipe amount needed per mortar
• 2 is 2kg or one whole clay
• 20 is 20kg or one whole heap of sand

Clay:

$Number=Mortar*.5$
$Kg=Number*1$

Heap of sand:

$Number=Mortar*.05$
$Kg=Number*1$

We need 2000 mortar

Clay:

• Number: 2000 * .5 = 1000 clay (2kg per) needed
• Kg: 1000 * 2kg = 2000kg of clay needed

Heap of sand:

• Number: 2000 * .05 = 100 heap of sand (20kg per) needed
• Kg: 100 * 20kg = 2000kg of heap of sand needed
