To make a scarf, jenny uses blue and white yarn. the number of yards of blue yarn she uses is 4 times the number of white yarn in each scarf. write 4 ratios to show the number of yards of white yarn to blue yarn for a scarf? 6th grade math question

Answer with Step-by-step explanation:

The number of yards of blue yarn Jenny uses is 4 times the number of white yarn in each scarf.

So, Ratio of yards of white yarn to blue yarn= 1:4

Multiplying the ratio by 2, we get 2:8

Multiplying the original ratio by 3, we get 3:12

Again multiplying the original ratio by 5, we get 5:20

Hence, 4 ratios to show the number of yards of white yarn to blue yarn for a scarf is:

1:4

2:8

3:12

5:20

b) 1/3 * 1/5
