Mathilda 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 pint of green paint. How much more paint will she need to buy.



Answer :

2/5 of 20 = 8. 

3/10 of 20= 6. 

8+6=14. So 20-14= 6

She needs 14 pints, so you subtract 6 from that. Your final answer should be 8 pints. 

Mathilda would need to buy 8 more pints of green paint

Further Explanation:

The given question is a typical number problem, and it deals with fractions and whole numbers. In order to derive solutions to numbers problem like the one given, some order of operations i.e. BODMAS would be used. BODMAS is an acronym of Bracket, Of, Division, Multiplication, Addition, Subtraction. The below given explanation would involve the use of BODMAS.

Solution:  

Total amount of pints she has = 20 pints

Amount she used to paint a landscape =

2/5 x 20 = 20 x 2 ÷ 5

  = 40 ÷ 5  

  = 8

Amount she used to paint a clover =

3/10 x 20 = 20 x 3 ÷ 10

    = 60 ÷ 10

    = 6

Total amount of used pints of green paint =

Amount she used to paint a landscape + Amount she used to paint a clover =

   = 8 + 6

   = 14

Remainder of pints =

Total amount of pints she has – Total amount of used pints of green paint =

   = 20 – 14  

   = 6  

Determining how much pints she will buy for her next painting:

For her next painting, she needs 14 pints

Her remainder = 6  pints

To derive how much pints she needs to buy, 6 pints would subtracted from 14 pints

  = 14 – 6  

  = 8

Therefore, the total amount of more pints she will buy for next painting = 8
