Question

the cost of 7/2metres of ribbons is rupees 255/4 .What is the cost of 1 metre of ribbon​

Answer 1

Answer:

Step-by-step explanation:

We need to divide

Start of Example:

The cost of 2 metres of wool is rupees 10. What is the cost of 3 metres?

Well, we need to apply the unitary method in this case. Remember, in the unitary method, we find out how much 1 of the items would cost when we are given the price of many.

Cost of 2 metres: 10 rupees

Cost of 1 metre: 10/2 rupees = 5 rupees

Cost of 3 metres: 5 × 3 rupees = 15 rupees

End of Example

So, we need to divide 255/4 by 7/2 to get the cost of 1 metre of ribbon.

255/4 ÷ 7/2

= 255/4 × 2/7

= 255/14

14 × 18 = 252

= 18 3/14
