I TRIED TO ADD IT AND GOT IT WRONG.

Answer 1

Answer:

(A)$1\frac{11}{15}$ yards

Step-by-step explanation:

On one hand, Noelle has $\frac{5}{6}$ of a yard of purple ribbon

On the other hand, she has $\frac{9}{10}$ of a yard of purple ribbon.

The length of ribbon she has altogether is determined by the sum of the two fractions.

We add $\frac{5}{6} and \frac{9}{10}$

$\frac{5}{6} + \frac{9}{10}$

Taking the Lowest Common Multiple of 6 and 10 =60

$\frac{5}{6} + \frac{9}{10} =\frac{(5X10)+(9X6)}{60} =\frac{(50)+(54)}{60}=\frac{104}{60}=1\frac{11}{15}$
