Question

During a sale, colour pencils were being sold in packs of 18 each and crayons in packs of 30 each. if you want full packs of both and the same number of pencils and crayons, how many of each would you need to buy ?​

Answer 1

Answer:

5 pencil packs and 3 crayon packs

Step-by-step explanation:

Hi

Number of colour pencils in a pack

= 18

Number of crayons in each pack = 30

If we find full packs of both which has same number of pencils and crayons

We have to find L C M of 18 and 30

18= 2 × 3 × 3

30 = 2× 3 × 5

L C M (32,24) = 2 × 3×3 ×5=90

18 pencils = 1 pack

i) 90 pencils = 5×18 pencils = 5 packs

ii) 30 crayons = 1 pack

90 crayons = 3 × 30 crayons = 3 packs

If want pencils and crayons same in number we have to buy 5 packs of pencils and 3 packs of crayons.

Hope this will helps you.

Answer 2

Hey mate hear is your answer

Number of color pencils in one pack = 24 No of crayons in pack = 32

Number of color pencils in one pack = 24 No of crayons in pack = 32

∴ The least number of both colours to be purchased = LCM of 24 and 32 = 2 × 2 × 2 × 2 × 3 = 96

Number of color pencils in one pack = 24 No of crayons in pack = 32 ∴ The least number of both colours to be purchased = LCM of 24 and 32 = 2 × 2 × 2 × 2 × 3 = 96

∴ Number of packs of pencils to be bought = 96/24 = 4 And number of packs of crayon to be bought = 96/32= 3
