Question

two ropes are 5/1/3 m abd 6 1/5 m long .find the total length

Answer 1

Hi ,

i ) Length of the

first rope = 5 1/3 m--( 1 )

ii ) Length of the

second rope = 6 1/5 m--( 2 )

Total length = ( 1 ) + ( 2 )

= 5 1/3 + 6 1/5

= 16/3 + 31/5

= ( 16 × 5 + 31 × 3 )/15

= ( 80 + 93 )/15

= 173/15

= 11 8/15 m

I hope this helps you.

Answer 2

Length of rope 5⅓

Length of rope 6⅕

Total length of rope 5⅓ + 6⅕

5⅓ = 16 /3

6⅕ = 31/5

LCM OF 3 , 5 = 15

80 + 93

____________

15

173 / 15 m

= 173/14 m = 11 8/ 15
