Question

marry bought 3. 1/2 ribbon she used 1. 3/4. to make a flower and used 1/2 m to decorate a table how much ribbon are left​

Answer 1

Length of remaining ribbon = 5/4

Step-by-step explanation:

Total length of ribbon – Length of ribbon used to make flower + used to decorate table.

$1 \frac{3}{4} + \frac{1}{2}$

$\frac{7}{4} + \frac{1}{2}$

$= \frac{9}{4}$

Length of remaining ribbon=

$3 \frac{1}{2} - \frac{9}{4}$

$\frac{7}{2} - \frac{9}{4}$

$= \frac{5}{4}$

Answer 2

Step-by-step explanation:

Total Ribbon used by Mary :

$1 \frac{3}{4} + \frac{1}{2} \\ = \frac{(4 \times 1) + 3}{4} + \frac{1}{2} \\ = \frac{7}{4} + \frac{1}{2} \\ \frac{7 + 2}{4} \\ = \frac{9}{4}$

∴ Ribbon left :

$3\frac{1}{2} - \frac{9}{4} \\ = \frac{(3 \times 2) + 1}{2} - \frac{9}{4} \\ = \frac{7}{2} - \frac{9}{4} \\ = \frac{14 - 9}{4} \\ = \frac{5}{4}$
