Answer:

83/8 yarns of red

Step-by-step explanation:

Given data

W are told that Suzzanah needs a total of 11 3⁄4 yards of yarn.

= 47/4 yards

Amount of blue needed

convert to simple fraction

1 3/8= 11/8 yards

Amount of Red needed

convert to simple fraction

4 1/2 = 9/2 yards

let us compute the number of yarns left out of the total

=47/4- (11/8+9/2)

=47/4- (11+36/8)

=47/4- 47/8

=94-47/8

=47/8 is the remaining yarn,

Hence the amount of red needed is

=47/8+9/2

=47+36/8

=83/8 yarns of red
