b
Step-by-step explanation:
Billy did 
of his homework on Friday and Saturday
Step-by-step explanation:
The given is:
- Billy did 1/6 of his homework on Friday
- He did 1/6 more on Saturday
- Billy still had 4/6 to finish
We need to find how much of his homework Billy did on Friday and Saturday
∵ Billy did 
of his homework on Friday
∵ He did more on Saturday
∵ He still had 
to finish
- That means Billy divided his homework into six equal parts, he
did 2 of them and still had 4 parts to do them
∴ He did = 
of his homework
∴ He did 2 parts of the homework from 6 parts
- Simplify the fraction by dividing up and down by 2
∵ 2 ÷ 2 = 1 and 6 ÷ 2 = 3
∴ He did = of his homework
Billy did of his homework on Friday and Saturday

The required mass of aquarium when it is half full of water is 10 kg.
Mass of the aquarium = 5kg
Length = 25 cm, width = 20 cm and height = 10 cm(when half filled)
<h3>What is volume?</h3>
Volume, is defined as the ratio of the mass of object to its density.
Since, density of the water = 1000 Kg/m³
Now Mass of the water = Volume x density
= 25/100 x 20/100 x 10/100 x 1000
= 0.005 x 1000
= 5 kg
Now, the total mass of the aquarium when half filed by water.
= mass of water + mass of aquarium
= 5 + 5
= 10 kg
Thus, the required mass of aquarium when it is half full of water is 10 kg.
