Answer 2

Answer:

A length of 1m 71cm in the ratio 11:8​ means 99cm: 72Cm

Step-by-step explanation:

A length = 1 m 71 cm

Convert in cm

100 cm = 1 m

So, 1m 71 cm = 100 + 71 = 171 cm

If the common multiple is x

then lengths are 11x and 8x

As per given condition

11x + 8x = 171

19x = 171

Divide both side by 19

19x ÷ 19 = 171 ÷ 19

x= 9

So, length = 11 (9) = 99 cm

And 8(9) = 72 cm
