If jenny wants to keep the ratio of blue yarn to white yarn the same, can she make a scarf using 42 yards of blue yarn? if so, how many white yarn will she need? if not, why not?

Hence, she needed 42 yards of white yarn.

Step-by-step explanation:

Since we have given that

Ratio of blue yarn to white yarn is same

i.e. 1:1

Number of yards of blue yarn she used to make a scarf = 42 yards.

So, number of yards of white yarn she needed to a scarf would be

42 yards.

as there is ratio of 1:1.

Hence, she needed 42 yards of white yarn.
