Further explanation
Given:
Mathilde has 20 pints of green paint.
She uses:
- ²/₅ of it to paint a landscape, and
- ³/₁₀ of it while painting a clover.
She decides that for her next painting she will need 14 pints of green paint.
Question:
How much more paint will she need to buy?
The Process:
Prepare ²/₅ to be ⁴/₁₀. The numerator and denominator are multiplied by two.
From the fractions ⁴/₁₀ and ⁵/₁₀ with the denominators of 10, we divided 20 pints into 10 parts for 2 units each.
The initial condition: [tex]\boxed{2}\boxed{2}\boxed{2}\boxed{2}\boxed{2}\boxed{2}\boxed{2}\boxed{2}\boxed{2}\boxed{2}[/tex]
²/₅ (or ⁴/₁₀) of it to paint a landscape: [tex]\boxed{2}\boxed{2}\boxed{2}\boxed{2}[/tex] which is four out of ten parts or [tex]\boxed{ \ 2+2+2+2=8 \ pints \ }[/tex]
³/₁₀ of it while painting a clover: [tex]\boxed{2}\boxed{2}\boxed{2}[/tex] which is three out of ten parts or [tex]\boxed{ \ 2+2+2=6 \ pints \ }[/tex]
From the scheme above, it appears that Mathilde has 6 pints remaining, i.e., [tex]\boxed{ \ 20-8-6=6 \ pints \ }[/tex]
She decides that for her next painting she will need 14 pints of green paint.
Thus, the amount of paint that she will need to buy is [tex]\boxed{\boxed{ \ 14 - 6 = 8 \ }}[/tex]. She needs 8 more pints of paint to buy.
