and
younger sister took 3 1/2of Ribbon .
what is the length of the Ribbon left over with your father ??​

Answer 1

Answer:

Length of ribbon bought by Sarita = \frac{2}{5}

Length of ribbon bought by Lalita = \frac{3}{4}

Total length of ribbon bought = \frac{2}{5}+\frac{3}{4}

LCM of 5 and 4 is 20.

= \frac{\left(2\times4\right)+\left(3\times5\right)}{20}

= \frac{8+15}{20}

= \frac{23}{20}

They bought 1\frac{3}{20}m of ribbon,.

Answer 2

Step-by-step explanation:

let length of ribbon left x

then,

x+9/2 + 7/2 =10

2x= 20 -16

2x= 4

x= 2

hence 2 mater ribbon left over with ur father
