Question

Varun has to make a model for a project for which he needs 15m of wire. The cost of 19/4m of wire rs 171/2. Find cost of wire needed for the project.

Answer 1

5 7/10

Explanation:

171/2 = 19/4

We divide

85 1/2 = 4 3/4

85 1/2/ 15 =

5 7/10 x 15/1 = 85 1/2

Answer 2

270

Explanation:

`(19)/(4) m \: equals \: 4 * (3)/(4) m \\`

So, each 4×3/4m costs 171/2

15m would cost???

`15 * (4)/(19) * (171)/(2) \\ = 270`
