Answer 1

AnswEr :

• Harika bought 15m of Cloth.
• She used 2m 30cm for a shirt, 3m 75cm for a pair of pants and 2m 60cm for a jacket.
• How much cloth left unused?

we can solve this Question by changing all the terms into either m or, cm.I'm going to change all the Terms into CM.we know that

⋆ 1 Metre ( m ) = 100 Centimeters ( cm )

• Let's Head to the Question Now :

⇀ Total Cloth Bought by Harika

⇀ 15 m

• we will change this into CM

⇀ ( 15 × 100 ) cm

⇀ 1500 cm

⇁ Total Cloth Used

⇁ 1 Shirt + 2 Pants + 1 Jacket

• measurements are given

⇁ (2m 30cm) + {2(3m 75cm)} + (2m 60cm)

• we will change this into CM

⇁ {( 2 × 100 ) + 30} + [2{( 3 × 100 ) + 75}] + {( 2 × 100 ) + 60}

⇁ {200 + 30} + [2{300 + 75}] + {200 + 60}

⇁ 230 cm + [2 × 375] cm + 260 cm

⇁ 230 cm + 750 cm + 260 cm

⇁ 1240 cm

_________________________________

• we will calculate Unused Cloth Now :

⇒ Unused Cloth = Total Cloth - Used Cloth

⇒ Unused Cloth = 1500 cm - 1240 cm

⇒ Unused Cloth = 260 cm or, 2.6 m

∴ Unused Cloth left is 260 cm or 2.6 m

◈ 2.6 Metre Cloth Left Unused ◈

$\blue {\huge {\boxed{ \frak{ Explanations :}}}}$

• Total Cloth Given is 15 m
• She used 2m 30 cm for a shirt, 3m 75 cm for a pair of pants and 2m 60 cm for a jacket.

• According to the Question :

$\Rightarrow\sf Unused \: Cloth = Total \: cloth - Used \: cloth$

$\Rightarrow\sf Unused \: Cloth=15 - (Shirt + 2 \: Pants + Jacket)$

$\Rightarrow\sf Unused \: Cloth =15 - (2.3 + 2 \times 3.75 + 2.6)$

• 30cm = 0.3m
• 75cm = 0.75m
• 60cm = 0.6m

$\Rightarrow\sf Unused \: Cloth =15 - (2.3 + 7.5 + 2.6)$

$\Rightarrow\sf Unused \: Cloth =(15 - 12.4) \: m$

$\Rightarrow \large\sf Unused \: Cloth =2.6 \: m$
