Question

Pam needs 2 yards of blue ribbon she has 0.497 yard she buys 0.91 yard more than she buys 0.4 yard of red ribbon how much more blue ribbon does Pam need?

Answer 1

Total ribbon Pam needs = 2 yards

Total ribbon Pam purchased = 0.497 + 0.91 + 0.40 = 1.807

The amount of ribbon Pam needs is calculated as,

$\begin{gathered} \text{Amount n}eeded\text{ = 2 - 1.807} \\ \text{Amount n}eeded\text{ = }0.193 \end{gathered}$

Thus the amount of ribbon needed is 0.193 yards .
