Answer 1

Answer:

• 22.5 kg of rice has 4.5 kg of sand mixed in it.
• The ratio of the quantity of sand to rice = 1: 5
• The ratio as a percentage is 20%

Step-by-step explanation:

Given :

The weight of the rice is  =  22.5 kg

The weight of the sand that is mixed in the Rice =  4.5 kg

Step 1: In order to find the weight you have to divide the sand with rice it means that

Here it is written in words: Sand: Rice  

Here we are doing the division that is  4.5: 22.5

$\frac{4.5}{22.5}=\frac{45}{225} \\=\frac{45 \div 5}{225\div 5} \\= \frac{9}{45} \\= \frac{9 \div 9 }{45 \div 9} \\=\frac{1}{5}$

So, the ratio of the quantity of sand to rice = 1: 5

Step 2: Express the ratio as a percentage

$\frac{1}{5} = \frac{1 \times 20}{5 \times 20} =\frac{20}{100} = 20 percent$
