Answer 1

Answer:

mark me brainliest

Step-by-step explanation:

total length of ribbon = 8 m

length of pieces cut = 23/10 + 19/5

= 61/10

= 6.1 m

length remaining = 8 - 6.1

= 1.9 m

Answer 2

$2 \frac{3}{10} \: + 3 \frac{4}{5}$

$\frac{(10 \times 2 + 3)}{10} = \frac{23}{10}$

$\frac{(5 \times 3 + 4)}{5} = \frac{19}{5}$

$\frac{23}{10} + \frac{19}{5}$

First do LCM of 10 and 5

LCM = 10

$\frac{23}{10} \times \frac{1}{1} = \frac{23}{10}$

$\frac{19}{5} \times \frac{2}{2} = \frac{38}{10}$

$\frac{23 + 38}{10}$

$= \frac{61}{10}$

Convert it into decimal point

$=6.1$

$8 - 6.1$

$=1.9$

Length of the remaining ribbon

$=1.9$
