Question

Please help with this!
I will need a clear explanation!

Answer 1

Willy can cover in 1L paint

`\\ \rm\rightarrowtail (13.5)/(3)=4.5m^2`

• 1st box should be filled with 4.5

Can cover in 10L

`\\ \rm\rightarrowtail 4.5(10)=45m^2`

Second one should be filled with 45

Answer 2

4.5 : 1

45 : 10

Explanation:

Given ratio: 13.5 : 3

To calculate equivalent ratios, we need to do the same operation to both sides of the ratio.

To reduce 3 L of paint to 1 L of paint, we need to divide by 3.

Therefore, we should also divide 13.5 by 3:

13.5 ÷ 3 : 3 ÷ 3

= 4.5 : 1

To increase 1 L of paint to 10 L of paint, we need to multiply by 10:

4.5 × 10 : 1 × 10

= 45 : 10
