Question

Colour 1/3 of the hats red.
Colour three-fifth hats blue.
(а)How many hats did you colour red?
(b)How many hats did you colour blue? .
(c)What part of the hats are not coloured?

Answer 1

Answer:

1/3 coloured red and 3/5 are coloured blue.

we have to find not coloured hat.

so here is how we can do it.

1/3 + 3/5 we have to make denominators same.

(1×5/3×5)+(3×3+5×3)

= 5/15 + 9/15

here we found that

5 hats are coloured red

and 9 hats are coloured blue.

5/1/+9/15 = 14/15

means 14 parts of 15 are coloured.

means 1 part is remaining to colour.

Answer 2

Answer:

(A) Total number of hats coloured red : 5

(B) Total number of hats coloured blue : 9

(C) Total part of hats that are not coloured : 1

Step-by-step explanation:

(A) Total number of hats = 15

1/3 of 15

1/3 × 15 = 5

So, 5 hats are coloured red.

(B) Now we need to find the number of hats that are colored in blue :

3/5 x 15 = 3x 3 = 9

Therefore, 9 hats are colored in blue.

(C) We know that, according to the question, 1/3 coloured red and 3/5 are coloured blue.

Therefore, we have to find not colored hat.

Solution :

1/3 + 3/5 we now make the denominators same.

(1×5/3×5)+(3×3+5×3)

= 5/15 + 9/15

here we found that

5 hats are coloured red

and 9 hats are coloured blue.

Therefore, we know that 9+5 hats are already covered blue ad red respectfully, therefore the total number of hats that are not colored :

15- (9+5) = 1

Means 14 parts of 15 are coloured.

Means 1 part is remaining to colour.
