Question

The ratios of Lycra to other materials in two stretch fabrics are 2:25 and 3:40. By changing each ratio to the form 1:n, say which fabric contains the greater proportion of Lycra

Answer 1

Material one (2:25)

Explanation:

Given that:

Lycra:Other material

2:25

3:40

Now, change it to the form of 1:n:

2:25 = 1:12.5

3:40 = 1:13.33

Now write proportions for each of them:

1:12.5 = 1/13.5

1:13.33 = 1/14.33

Now compare:

1/13.5 > 1/14.33

Hope this helps good luck
