equal pieces. Find the length of each piece.
Answers
Answer:
3)12 1/6
4)2 3/16
Step-by-step explanation:
3) initial price of potatoes = 10 2/3 = 32/3
Rise in price of potatoes = 1 1/2= 3/2
New price = 32/3+3/2
New price = 64/6+9/6
New price = 73/6 = 12 1/6
4)
Length of whole wood = 8 3/4m= 35/4m
As it is cut into 4 pieces we shall divide it by 4
35/4 ÷ 4
35/4×1/4
=35/16
=2 3/16
Answer:
Question (1):
Given:
• Manali bought potatoes at the rate of rupees 10 2/3
per kg on Monday.
• On Tuesday, the price of potatoes increased by rupees 1 1/2per kg.
Find:
• What was the cost of potatoes on Tuesday?
According to the question:
• 10 2/3 = The rate Manali bought the potatoes.
• 1 1/2 = The price of potatoes increased.
• Let us assume 'x' as new price.
Well, we can write 10 2/3 as 32/3 and 1 1/2 as 3/2.
Using formula:
• The rate potatoes brought (+) The price of potatoes increased.
⇒ x = 32/3 + 3/2
⇒ x = 64/6 + 9/6
⇒ x = 73/6 + 12 1/6
Therefore, 12 1/6 is the new price on Tuesday.

Question (2):
Given:
• A piece of wood 8 3/4m long is cut into four
equal pieces.
Find:
• Find the length of each piece.
According to the question:
• 8 3/4 = Total length of the wood.
• It is divided into four equal parts.
Well, we can write 8 3/4 as 35/4 m.
Using formula:
• Total length of the wood (÷) Divided four parts.
⇒ 35/4 ÷ 4
⇒ 35/4 × 1/4
⇒ 35/16
⇒ 2 3/16
Therefore, 2 3/16 is the length of each piece.
