Question

Rita bought 2 piece of ribbon measures by 9/10​

Answer 1

Answer:

I believe you were asking what is the total measure of these ribbons, so here is the answer:

Pieces of ribbon: 2

Measure of each ribbon: 9/10 units

Measure of both the ribbons: 9/10 x 2

= 18/10 = 1.8 units

Answer 2

Step-by-step explanation:

The total length of ribbon = 4½ m = 4.5 m

= 4.5 m x (100 cm/1 m)

= 450 cm

The number of pieces of ribbon, each 4.5 cm long, that can be cut from a length of 4½ m (450 cm) = 450 cm/(4.5 cm/1 piece)

= (450 cm/1)/(4.5 cm/1 piece)

= (450 cm/1)(1 piece/4.5 cm)

= (4500 cm-pieces)/45 cm)

= (4500 cm/45 cm) pieces

= 100 pieces
